Brown eye color 1. What colors are eyes?

As you know, it consists of many layers. Behind the transparent cornea goes choroid- in the front part it has an iris, which in turn contains chromatophores in one of its cell layers. In them and. On its own, it ranges from to dark brown to black. How then do you get blue, cyan or green?

The answer is quite simple: it all depends on the amount of pigment and the density of the fibers of the outer layer of the iris. Thus, a rich blue tint is obtained due to a combination of low density collagen fibers and low melanin content. The fibers themselves are white, the color appears due to the scattering of light in the corneal stroma. Blue and gray are formed in a similar way, the only difference being that the fibers are denser, so the iris is lighter.

The green tint is extremely rare. It is associated with small amounts of the yellow pigment lipofuscin and low melanin content. A color that should be blue or blue mixes with lipofuscin to produce green.

Finally, black and shades of brown are obtained only with a high melanin content. Brown color is the most common color in the world. Most owners of such eyes are concentrated in South-East Asia, Africa, Oceania, South America and in southern Europe.

Eye color: interesting facts

All children Caucasian are born with light, usually blue, eyes. However, after three to six months the shade may change. The final color of the iris is determined only in the early adolescence, by about 10-12 years. The eyes may seem to “fade” - this is due to dystrophic processes that cause depigmentation.

Eye color can also change as a result of a number of diseases, such as glaucoma, siderosis, leukemia and lymphoma.

Why do people different colour eye? Human eye beautiful and unique - it is specific like a fingerprint. Therefore, it is not surprising that many are so obsessed with the issue of eye color and its influence on people’s character.

“The eyes are the mirror of the soul.” Is this really so and what do we know about them?

Eyes are sensory organ, through which we receive more than 80% of the information from the outside world. This is possible due to the presence of photoreceptors in them:

• cones;
• sticks.

Rods help people navigate in the dark, and cones respond to light. To what color are the retinal cones selectively sensitive? Cones are sensitive to blue, green and red wavelengths of light. It is this color spectrum that is the basis for our color perception.

Factors in the formation of iris color

Everyone's eye color is different and ranges from very light shades to very dark ones. Although genetics plays a dominant role in determining the color of the iris, like many other genetic characteristics, it is not so simple.

So what determines a person’s eye color? It is generally accepted that children inherit iris color from their parents. In fact, color inheritance is more difficult process– polygenic. This trait is influenced not by one gene, but by several. Moreover, this is not the only factor that shapes color.

1. Melanin.

To find out what eye color a person has, just look at the color of his iris. It is determined by the content and size of the pigment fibers responsible for color - melanin.

At birth, children have not yet produced a sufficient amount of this color pigment, so many newborns have gray-blue eyes (they are also called “milky”). Gradually, melanin accumulates, and the baby acquires its natural eye color, inherent in it by genetics.

Melanin is present in both the anterior and posterior layers of the iris. However, the pigment content in its frontal part determines the decisive importance.

People with blue eyes do not have melanin, so in fact their iris color is just an “illusion”, which acquires a shade due to the property of Rayleigh light scattering.

Carriers dark eyes have great content melanin, and people with green eyes have less pigment than brown-eyed people, but more than blue-eyed people.

At very large cluster melanin in the iris, it acquires a very dark shade, creating the effect of black color.

2. Genetics.

Eye color is determined by eight genes. The most responsible is the OCA2 gene, located on chromosome 15. It produces a protein called P protein, which helps create and process melanin.

Every person has two copies of each gene in their DNA: one copy inherited from mom and one from dad. The dominance of one copy of a gene over another means that the dominant copy determines the color of the iris, and the properties of the other gene are suppressed.

The combined function of a number of other genes can increase melanin in the eyes to more high level than either parent, which explains how parents with light-colored irises sometimes give birth to dark-eyed children.

Interesting! Recent studies have shown that Blue colour The eye only occurred in the last 6,000 to 10,000 years and is a genetic mutation.

Colors of the iris

So, what types of eyes are there? Which eye color is the rarest and which is the most common? And also, what is the name of the condition when the color of the iris of one eye is different from the other? Let's look at the different colors of the iris of the human eye.

Brown eyes

Chestnut is the most common eye color in the world. Most of the world's population are its carriers. Color is determined high content pigment and the dominant gene in the pair.

In humans, right-handedness dominates over left-handedness, and brown eye color is the most common color among the population.

A lot of brown-eyed people live in African and Asian countries.

They are considered a mixed eye color - only about 5-8% of the world's population are carriers of it. The color has high concentration pigments are closer to the center and less at the borders, which creates the effect of a multi-colored iris: from yellow-green to brown.

Blue eyes

Blue eyes are caused by mutation and are therefore much less common throughout the world. This color is determined complete absence melanin.

The blue color of the eyes is due to Rayleigh scattering as it reflects light from the iris.

Interesting! Scientists recently discovered a fact: people who have blue eyes descended from the same ancestor!

Due to the mixed racial groups, blue eyes having recessive genes, are becoming less and less common. Largest quantity carriers are concentrated among nationalities located near the Baltic Sea in northern Europe. According to various estimates, about 8% of the world's population are their carriers.

This is the most rare color eyes in the world, only about 2% of the world's population have them. Today, about 7 billion people live on the planet, which means that only 140 million of them are green.

They are often confused with swamps, but it is completely different - more distinct and concentrated. Green eye color is due to a small amount of pigmentation in the eye. The combination of golden with natural blue light scattering results in this color.

Most common in European countries, as well as in Western Asia.

Attention! Those with green eyes are more susceptible to harmful effects rays of the sun. This is due to the previously mentioned pigment melanin. Simply put, people with this iris color more likely development certain types cancers such as intraocular melanoma.

People with light eyes should definitely wear Sunglasses outdoors during periods of strong sun exposure.

Grey eyes

Gray eye color can be mistakenly considered a shade of blue. "Silver" eyes are the result of low melanin content and reflect gray-silver appearance. They tend to have brownish-golden spots and can vary from gray to blue and green due to environmental conditions and emotional state.

Light and dark gray color is typical for natives of Eastern European countries, and it can also be classified as rare.

Amber eyes

A shade of yellow-copper tone that results from pigment yellow color. Amber eye color is also very rare.

They are most common in Asian countries and southern America. The color of this eye color can vary from golden yellow to a more copper tone.

This effect can be found with a mutation when melanin is completely absent (for example, in albinos). As a result, blood vessels are strongly emphasized.

The red color you see in this image is a reflection of the flash at the back of the iris, which is filled with blood vessels.

This unusual coloration of the iris is caused by a genetic mutation. This deviation is called “born in Alexandria.” There are many legends associated with this color, the confirmation of which no one has ever found.

The first case was recorded in the 1300s. The deviation does not affect the quality of vision.

Heterochromia

You must have heard about people who have eyes of different colors?

A condition in which one eye acquires one color, and the other has another, is commonly called heterochromia.

It is believed to be caused by mutations in the genes responsible for melanin distribution, which are often altered due to chromosomal homogeneity. The picture shows a woman with different eye colors: one is dark brown, the other is blue-gray.

What does your eye color say about you?

What is the meaning of eye color and what can they tell about a person?

It is believed that the eyes do not lie. One way to “read the truth” is to study the color of the human eye.

So, what does eye color mean and how does it affect temperament?

1. Dark brown – what does this eye color say about its owners?

Owners of such eyes can act tough and cold-blooded, while at heart they are quite sensitive natures. They combine confidence, simplicity and modesty.

People with brown eyes are considered wonderful lovers. Carriers brown eyes dark shades are known for their leadership abilities and are less likely to succumb to various addictions. They have enormous mental power.

2. Green eye color and its secret.

The rarest eye color in the world is possessed by persistent and stubborn people who always defend their point of view. They adapt well to any conditions. This eye color in a person causes universal admiration, so such people are accustomed to increased attention to yourself. They are distinguished by their honesty and secretive nature.

3. Blue color of the iris - what does it mean?

Blue iris color is the second most common color in the world. People with blue eyes are believed to be immune to pain and have a high pain threshold. They also demonstrate excellent endurance and developed analytical thinking. Patient people have this eye color.

4. Black color of the iris - the meaning of this eye color?

People with black eyes are very reliable. They are good secret keepers - you can trust them. They are very responsible and friendly. They are able to withstand pressure and not change under the pressure of time and circumstances, and are also not susceptible to emotional shocks. People with black eyes are considered very good advisors.

5. Light eyes.

People with light eyes are very sensitive to the pain of others, while also being even more vulnerable to their own. They will always come to the rescue and are good comforters. People with lighter shades of eyes (light gray, light blue or light green) are funny, helpful, and friendly. They can easily cheer up and are great optimists.

6. Swamp color and what it means

Hazel is an unusual eye shade, but if you own it, you've hit the jackpot. All in one: brown, yellow, green, each of which makes its contribution. Such people are strong, sensitive and hidden, have enormous physical strength and endurance.

7. Gray eye color and what it indicates.

People with gray eyes sometimes suffer from intense internal conflict, they often find it difficult to make decisions, and they are prone to constant skepticism.

Is it possible to accurately determine a person's character by eye color? Of course, no one will give you a 100% guarantee. Each person is a unique individual with his own set of characteristics, abilities and inclinations, regardless of the color of our eyes. But to trace some patterns of similarity in the behavior of people with general color you can, and it’s hard to ignore.

Change in iris color

Can eye color change? Many people are curious whether the iris can acquire a different color and why eye color changes.

Reasons why eyes change color:

• light scattering;
• mood;
• health or medical reasons;
• with age.

There are diseases causing change iris color. For example, Fuch's heterochromic iridocyclitis, Horner's syndrome, or pigmentary glaucoma often cause changes in eye color.

Attention! In situations where your eye color changes suddenly for no apparent reason and your pupils remain dilated for long period time, consult a doctor immediately. This may have serious reasons, and consulting an ophthalmologist will not hurt you.

Also some medications from glaucoma can cause changes in the color of the iris. Eye drops prescribed for glaucoma can affect the shade of the iris, changing it to a darker side.

In 10-15% of Caucasians, eye color changes with age. The brown color of the iris may lighten or, on the contrary, darken over the years.

Other factors:

• Lighting. Sun rays or artificial lighting can affect the perception of how the color of the iris is seen: the intensity of the light will either enhance or soften the tone of the eyes.
• Reflective colors. The color of objects around you can enhance the color of your eyes.
• Makeup. Some girls apply colored eye shadow to emphasize or highlight the color of the iris. It can also cause a chameleon eye color effect, where the iris changes hue to match the makeup shade.
• Allergic reactions. If people are allergic to blooms or for other reasons, their pupils become constricted, which can lead to a change in the shade of the pupil.
• Emotional condition. While it doesn't directly change your eye color, what you feel at any given time can affect how your eyes are perceived. In particular, if you are depressed or crying, your pupil may dilate, compressing the color pigment, causing the iris to appear darker.
• Various substances. The use of alcohol and drugs also causes the pupils to constrict or dilate, changing the intensity of their color.

Eye color change surgery

Is it possible to change your eye color yourself? When someone wants to improve their vision, they can try contact lenses or use the services eye surgery. But what if they want to change the color of their iris? How to change eye color?

If for some reason you are unhappy with your eye color, you can use colored contact lenses.

Attention! Don't buy them online or borrow them from a friend - you risk getting an eye infection. The best option There will be an ophthalmologist consultation.

If you want to solve the issue more radically and change the color completely, then today there are technologies that can offer those who want one more service - this is an operation to change eye color.

This operation involves inserting a colored implant into the eye. The procedure is painless and does not require anesthesia. In just a few minutes the patient acquires the desired color. The implant can subsequently be removed.

Another method of surgery is laser burning of melanin to form light eyes. This method is not yet widely practiced. The procedure takes no more than 30 seconds, and within a few weeks you will have a completely different eye color. It should be noted that this is forever and it will not be possible to return the previous color.

How do you get green eyes?

To understand this, you will have to seriously complicate the diagram described in the first paragraph. Do you really need this?

Okay, let's go. The function of melanin is to absorb ultraviolet light from the sun, which is harmful to cells. In company with ultraviolet light, melanin partially absorbs just violet, as well as blue and cyan, therefore, it reflects everything else, from green to red - and this reflected mixture has a brown (brown) color.

The iris consists of five layers. In the fifth, most inner layer, all people contain a lot of melanin (except for some albinos), this layer is called the pigment layer. In addition, melanin can also be contained in the second, outer layer - the color of the eyes actually depends on its quantity and distribution:

• if there is a lot of melanin in the outer layer, then all the light will be reflected only from it and the eyes will brown;

• if there is no melanin in the outer layer, then light will be reflected from the inner layer and the eyes will blue(why - see below);

• if there is very little melanin in the outer layer, then the blue light reflected from the inner layer will be slightly darkened, and the eyes will appear gray;

• if the outer layer has an average amount of melanin, then the yellow light reflected from the outer layer will mix with the blue light reflected from the inner layer, and the total will be green.

How do you get blue eyes?

I repeat: the iris of the eye contains two pigment layers; The blue color is obtained if there is no melanin in the front layer at all. In this case, the light is reflected only from the back layer, and then passes through tissue(4 layers of the iris lying in front). It is reflected brown, but our fabrics actively absorb red light and transmit blue light, so the output is blue.

Compare: skin capillaries lie close to the surface, so they look red to us (their color does not change). And the veins, like the pigment layer of the iris, lie in the depths, so they appear blue: the blood there, of course, is not blue, but dark red, but as long as the red light passes through the tissues, it turns into blue.

You can even try an experiment: take a test tube with blood and put it in a glass of milk. Milk, like (other) our tissues, absorbs long-wave (red) rays more strongly, so red blood “through milk” will appear blue.

When meeting a person, probably everyone would like to know what to expect from such people or how to behave correctly with them in order to achieve what they want. It is worth considering that not only actions, but also facial expressions and gestures can tell a lot about a particular person. Probably, many have heard such an ancient expression as “The eyes are the mirror of the soul,” but few have thought about whether this is true or not. Just by looking into a person’s eyes, you can understand and see a lot about him, of course, if you know exactly how to look correctly.

How to determine the influence of eye color on a person’s character?

Eye color is given to a person from birth and can change at the moment when we ourselves change. Today you can easily and quickly change your eye color using contact lenses, but at the same time there are often cases when a change in the natural color of the eyes occurs. As a rule, this phenomenon is directly related to changes that affect mental condition and morals.

Scientists have concluded that the more intense and brightly expressed the color of the eyes, the more pronounced they will be. human passions, filling with energy and taking an active life position. Consequently, the lighter the shade of the eyes, the more romantic and tender the person’s soul.

The intensity and brightness of the color in the iris indicates precisely the creative beginning of the individual. Gentle natures are characterized by warm shades of eyes, while cold shades speak of a firm and persistent character.

Black eyes

Black-eyed people are optimists, at the same time they are very responsible and reliable, but at the same time they are also distinguished by their mystery and rather secretive character, which makes it very difficult for them to open their souls even to close friends.

If serious difficulties or problems arise, they can show strong aggression and irritability, at the same time they are not able to harbor a grudge for too long and quickly forget it.

People with black eyes are always confident and own strength, while they are characterized by fearlessness and innovative thinking, but they can be very amorous. Such people are characterized by a very hot temperament, sensitivity and sexuality, which is difficult for representatives of the opposite sex to resist.

Such people always know what to do to please others, they can radiate warmth and charm, and love to be in the center of all events. Black-eyed individuals are very selective in people, but at the same time remain demanding of others, as well as of themselves. Such individuals cannot sit in one place for too long, because they are very enterprising and passionate, they always want to be the first in everything, which they constantly prove in practice.

Brown eyes

Brown-eyed people love to be the center of attention always and everywhere, because their life is not just one big play, but a real one-man show, where those around them act as scenery.

Often such people crave power, while they are very enterprising, gambling and can be aggressive if they do not get what they want in a timely manner. Despite the fact that these individuals are too touchy, they also quickly leave behind all grievances.

People who are close to brown-eyed people cannot get rid of unpleasant sensation that they constantly live on a powder keg, because they simply do not know what can be expected from them.

Owners of brown eyes amaze others with their attractiveness, sociability, wit and sensuality. The darker the eye shade, the more pronounced all the character traits listed above are.

Light brown eyes

These individuals are very hardworking pragmatists who constantly strive for isolation, while they do not tolerate advice and instructions. Owners of light brown eyes love to reflect on the essence of existence. Quite often their tendency to laziness is so high that it exceeds all limits.

But, despite their laziness and passivity, these people have a truly unique ability to easily and quickly complete even the most difficult tasks. difficult tasks, showing incredible productivity, at the same time they hardly bother.

From the outside it may seem that people with light brown eyes are very soft and pliable, but they like to do everything the way they want and almost never agree with the opinions of others.

Yellow eyes

Yellow eyes are always good and faithful friends, while not a single obstacle can stop them if close person found himself in trouble and needs their help. But such individuals are often very insidious and mysterious, and therefore can become dangerous opponents.

These people will never accept a situation in which someone will impose their own rules. They have poor control over emotions and perfectly sense insincerity, lies and falsehood in the words of their interlocutor. Men with yellow eyes become brave defenders and faithful comrades for their chosen ones.

Tiger yellow eyes

It is believed that people with exactly this eye color have well-developed intuition, so it is very difficult to confuse them. Such individuals are their own masters, but they are very wary of strangers.

Thanks to their excellent artistry and natural flexibility, they can easily and simply get out of any situation. unpleasant situations and conflicts, but do not put their own person at risk at all. Such people are very vindictive and vindictive, and therefore become extremely dangerous enemies.

Green eyes

Green-eyed people have well-developed intuition, and for them it is very important precisely the firm confidence that all the actions they perform will lead to a visible effect and will not be in vain.

Gray-green eyes

These individuals are very determined and patient pragmatists, conscientious and hardworking. People with gray-green eyes are devoted and tender with their significant other, and they can spend all their energy searching for the chosen one, but they choose only once and for all. If you need to solve something serious and important question, they will show firmness and toughness, at the same time they know how to listen well.

Gray-green-blue eyes

Grey eyes

These individuals are almost never in a hurry, and at the same time they are rarely late. They are very secretive, do not like to make their problems public, and try not to show their feelings in public.

People with gray eyes prefer cold calculations, so they almost never rely on their own intuition. If you have to solve a problem, especially when it requires intelligence, no one can cope with the task better than the grey-eyed ones.

They have a reserved and dry character, which can cause certain difficulties associated with emotional sphere. Gray-eyed people try to find inspiration in their close surroundings and become completely happy if there is a person nearby who can fill them bright emotions. Very faithful in love, they extremely rarely cheat on their chosen ones.

Blue eyes

Blue-eyed people love to get into disputes and conflicts, because they get indescribable pleasure from the process itself, since it is very important for them to prove to everyone around them that they are right and aware of any issue.

Disputes and conflicts are the element of blue-eyed personalities, and they are subjective in them, because first of all they will be guided only by their own dislikes and likes, but not by common sense.

Blue eyes

Excessive sentimentality is clearly visible in the character of such people, but this does not prevent them from having numerous affairs and affairs. It is because of this that it can be very difficult for blue-eyed individuals to find true love in their lives.

They are very vulnerable and sensitive, quickly get offended, and can lose their temper at lightning speed, so it will be difficult for close people to atone for their guilt before them. Such individuals can, even many years later, accurately reproduce the words and intonation that offended them.

The mood of blue-eyed people changes quite often, due to the fact that they are prone to strong emotions and can succumb to depression, even if there is absolutely no good reason for this.

Such individuals may have not just diverse, but also unexpected talents. The main distinguishing feature of blue-eyed people is that they are able to adapt almost instantly to absolutely any conditions.

People with such interesting eye colors are prone to sudden changes mood, as well as variability in own desires. The fact is that each shade will make some specific adjustments to the personality.

People with chameleon eyes are able to easily and quickly integrate into a variety of life circumstances, simply adapt to new conditions, practically without experiencing a feeling of discomfort. These individuals are very consistent in their actions, they like organization in everything, however, despite this, they most often act impulsively and spontaneously, which makes them completely unpredictable.

For more information on how eye color affects character, see here:

Eye color has great importance in a girl's life, even if we don't think about it. Very often, clothes and accessories are chosen directly to match the color of the eyes, not to mention the fact that thanks to existing stereotypes, we, to some extent, form our initial opinion about a person taking into account the color of his eyes.

Therefore, when special lenses appeared that changed eye color, many girls rushed to purchase them in order to create images with different colors eye. And besides lenses, Photoshop helps us, with its help you can achieve any color, but unfortunately this is displayed only on the monitor screen and photographs.

What determines the real color of a person's eyes? Why do some people have blue eyes, others green, and some even boast purple ones?

The color of a person’s eyes, or rather the color of the iris, depends on two factors:

1. Density of iris fibers.
2. Distribution of melanin pigment in the layers of the iris.

Melanin is a pigment that determines the color of human skin and hair. The more melanin, the darker the skin and hair. In the iris of the eye, melanin ranges from yellow to brown and black. In this case, the back layer of the iris is always black, with the exception of albinos.

Yellow, brown, black, where then do the blue and green eyes come from? Let's look into this phenomenon...

Blue eyes
The blue color is due to the low fiber density of the outer layer of the iris and the low melanin content. In this case, low-frequency light is absorbed by the back layer, and high-frequency light is reflected from it, so the eyes turn out blue. The lower the density of the fibers of the outer layer, the richer the blue color of the eyes.

Blue eyes
Blue color occurs when the fibers of the outer layer of the iris are denser than in the case of blue eyes and have a whitish or grayish color. How higher density fibers, the lighter the color.

Blue and blue eyes most common among the population of northern Europe. For example, in Estonia up to 99% of the population had this eye color, and in Germany 75%. Only given modern realities, this situation will not last long, because more and more people from Asian and African countries are trying to move to Europe.

Blue eye color in babies
There is an opinion that all children are born blue-eyed, and then the color changes. This is a wrong opinion. In fact, many babies are actually born light-eyed, and subsequently, as melanin is actively produced, their eyes become darker and the final eye color is established by two to three years.

Grey colour it turns out similar to blue, only in this case the density of the fibers of the outer layer is even higher and their shade is closer to gray. If the fiber density is not so high, then the eye color will be gray-blue. In addition, the presence of melanin or other substances gives a small yellow or brownish impurity.

Green eyes
This eye color is most often attributed to witches and sorceresses, and therefore green-eyed girls are sometimes treated with suspicion. Only green eyes were obtained not due to witchcraft, but due to a small amount of melanin.

In green-eyed girls, yellow or light brown pigment is distributed in the outer layer of the iris. And as a result of scattering by blue or cyan, green is obtained. The color of the iris is usually uneven, there is a large number of various shades of green.

Purely green color The eye is extremely rare; no more than two percent of people can boast of green eyes. They can be found among people in Northern and Central Europe, and sometimes in Southern Europe. Women have green eyes much more often than men, which played a certain role in attributing this eye color to witches.

Amber
Amber eyes have a monotonous light brown color, sometimes with a yellowish-green or reddish tint. Their color can also be close to marsh or golden, which is due to the presence of lipofuscin pigment.

Swamp eye color (aka hazel or beer) is a mixed color. Depending on the lighting, it may appear golden, brown-green, brown, light brown with a yellow-green tint. In the outer layer of the iris, the melanin content is quite moderate, so the marsh color is the result of a combination of brown and blue or blue flowers. Yellow pigments may also be present. Unlike amber color eye, in in this case The coloring is not monotonous, but rather heterogeneous.

Brown eyes
Brown eye color results from the fact that the outer layer of the iris contains a lot of melanin, so it absorbs both high-frequency and low-frequency light, and the reflected light adds up to brown. The more melanin, the darker and richer the eye color.

Brown eye color is the most common in the world. But in our life, this - which is a lot - is valued less, so brown-eyed girls sometimes envy those to whom nature has given green or blue eyes. Just don’t rush to take offense at nature, Brown eyes– one of the most adapted to the sun!

Black eyes
Black eye color is essentially dark brown, but the concentration of melanin in the iris is so high that the light falling on it is almost completely absorbed.

Red eyes
Yes, there are such eyes, and not only in the movies, but also in reality! Red or pinkish eye color is found only in albinos. This color is associated with the absence of melanin in the iris, so the color is formed based on the blood circulating in the vessels of the iris. In some in rare cases The red color of blood, when mixed with blue, gives a slight violet tint.

Purple eyes!
The most unusual and rare eye color is deep purple. This is extremely rare, perhaps only a few people on earth have a similar eye color, so this phenomenon has been little studied, and there are different versions and myths about this that go back centuries. But most likely purple eyes do not give their owner any superpowers.

This phenomenon is called heterochromia, which translated from Greek means “different color”. The reason for this feature is different quantities melanin in the irises of the eye. There is complete heterochromia - when one eye is one color, the other - another, and partial - when parts of the iris of one eye are different colors.

Can eye color change throughout life?
Within one color group color can change depending on lighting, clothing, makeup, even mood. In general, with age, most people's eyes lighten, losing their original bright color.
