What is it that makes the color in people's eyes?

The genes for eye color determine the amount of melanin, a dark brown pigment, produced in the iris of the eyes. Blue eyes are due to a lack of melanin, while brown eyes indicate melanin-rich irises. Thus, people with darker hair and skin have higher levels of melanin and tend to have brown eyes, while people with lighter hair and skin have lower levels of melanin and usually have lighter colored eyes.

On a more scientific basis they just discovered that humans have a wide varity in the ratio of color receptors in the eye.  Some have mostly red color receptors, some have lots of green and blue.  I'm guessing that this could affect how we individually precieve color and influence our preferences.  Anyways, you might find the "dewey color system" interesting and it might offer you more insight.  http://www.deweycolorsystem.com/

i think ur talking about skin pigmentations, in humans, melanin is what gives us our skin color.

It's genetic in most people.\n\nThe second main cause is a change in melanin levels in one eye, this can be because of illness or trauma to the head.\n\nFor others a trauma to the head can jolt the blood vessels in the eye causing a change in colour

I believe eye color is sex linked.  I think wing structure is too (like normal versus vestigial).

Eyes are the clear winner for me.  I love looking at people's eyes.. are they curious, mischevious, sexy, and the infitine colors.  Plus, I have to admit to liking people that make and maintain eye contact while they talk with you. To me, it's respectful to do that.   I also love any color eyes and wathcing them light up with love, laughter, joy and life.

For the same reason that some people have brown eyes and others have blue. Its the type of plant they are.

whatever the color of your eyes are

Yes, the colour of the eyes can change by using contact lenses. I don't know if it can change by a physical way.

Eye color is a polyploid trait.  the actual genes occur on a couple of different chromosomes.  Sorry.  The human genome project has it mapped out which chromosomes they are my poster is at work.

It's the way the molecules are formed in any particular "color" item and the light that gets absorbed by those molecules.  The light that doesn't light absorbed is the color you see.

This is what I found about eye color changes.  For complete articles see the web sites in sources below.\n\n"A surprising new study found that 10% to 15% of whites undergo changes in eye color during adolescence and adulthood, according to a report in the Archives of Ophthalmology."\n\n"The mechanisms that control these changes in iris color remain unknown. But researchers believe that it may be due to changes in production from melanocytes, cells found in the hair, skin and the eye that make melanin, a black or brown pigment.\n\nMore study is needed to confirm that the eye change is true age-related change in color and not due to illness or a flaw in the study. One report has suggested that macular degeneration, the leading cause of blindness in older adults, can be accompanied with a lightening of eye color with age, the authors noted."\n\n"Ask a doctor to examine your eyes if you notice a slow loss of color. The change could be due to Fuch’s heterochromic iridocyclitis, Horner’s Syndrome, and pigmentary glaucoma."

I have a friend who can see these orbs, or auras, arround people very well.  I have been with her as she has explored it more latley.  As far as we have been able to tell, the colors you see are specific to your sight.  Also they are specific to the person and the mood, state of mind or things the person you are observing are going through. If you want you can google "about auras" to see what some people have written about it.  I think this is something that you must explore by just observing people, use your friends, ask them what they are going through and see if that associates with their color at that time.

Don't know what you are talking about but , different colors look different on different people, whether man or woman everyone has  a certain color that looks good with their skin tone or eye color.  You just have to experiment

I'm not really sure, but from what I understand it to could be some chemical changes in the body based on your feeling and what horomones your brain is releasing. My teacher told me that some teenagers have eyes that change color because of hormonal changes, and when they become adults, their eyes will probably remain one certain color. \n\nIf you are interested in eye genetics here is a link:\nwww.anthro.com/evo/inherit.html\n\nMy eyes are completely brown and my favorite eyes are blue.

Pigments in your eyes serve the purpose of screening out excess light.  All eyes "should" be brown.  Genetic defects in certain pigments results in a variation of eye color either by incorrectly transcribing pigments or not expressing genes that should be expressed.
