The amount of pigment in the eyes
the colour spectrum works like this ranging from the least amount of pigment to the most amount of pigment
red/pink (albino's), violet (also present in albino's, debatable existence in non-albino's), blue, grey, green, amber, true hazel, brown, black/very dark brown (non-caucasians)
Amber is the center of the eye colour spectrum being the lightest brown eye, so all eyes darker than amber are closer to black/very dark brown and all eyes lighter than amber are closer to blue.
However red/pink isn't really an eye spectrum colour due to it only found in albino's (because they have no pigmentation and you're seeing the blood vessels at the back fo the eye) and people with blood leakages in their eye, and violet (very rare) and grey are both shades of blue, and amber, true hazel and black/very dark brown are all shades of brown, so technically there are only 3 true eye colours, blue, green and brown, the rest are basically significantly different shades of the 3.
note: true hazel eyes are a light golden brown colour (basically light brown) they can contain minimal green (either within the gold and/or around the edges of the eye) but green is by no means a requirement for true hazel eyes. True hazel eyes are not just any eye that contains both green and brown in the same iris. If you class hazel eyes as being green with brown then they come under the green category and are therefore lighter than amber.
Eye color has nothing to do with one's general health. Health depends upon your lifestyle, genes, environment and your ability to comprehend nutrition and healthy living.
Brown eyes.
No.
No.
Brown eyes are dominant. That's why more people have brown eyes then hazel or blue or green.
It is impossible for a baby to have brown eyes if both of his parents have blue eyes since the brown eye gene is more dominant.
i have blue eyes & my pupils are big
auburn hair and green eyes is more rare than brown hair with blue eyes
not necessaryly. The more melatonin you've got in your eyes, the darker is its color. Now, with dark eyes you're best prepared for locations where the sun is shining bright, cause there won't pass as much light to your retina as if you had blue eyes. On the other hand, people with blue eyes have an advantage in areas with dim light, because their iris lets more ligth through and so they may be ready to see light where people with darker eyes still can't do so. In short: In Africa people profit from brown eyes wheras people in Skandinavia do so with blue eyes.
Blue eyes are a comparatively recent mutation. They're regarded as more attractive than brown eyes an so confer a mating and reproductive advantage. In short, people with blue eyes tend to be more successful in the mating game and produce more children.
NO. People with blue eyes do NOT have the brown eyed gene, if they did they themselves would have developed brown eyes instead of their blue as it is dominant. So two blue eyed parents can only pass the blue gene to their offspring.
Because it is not a request, Like; please don't make my brown eyes blue. It's more of a musing "Doesn't that just make me sad." "Doesn't it make my brown eyes blue" "Don't it make my brown eyes blue".
His eyes are hazel, but more green than brown.
Yes Of Course-- Edit --Yes, all people have 2 sets of genetics for eye color. Their actual eye color and one other which is more than likely determined by their parent's eye colors.So, if a couple where one person has blue eyes and the other has brown eyes has a child that has blue eyes that child has a 2nd gene which is likely brown, therefore their child can have brown eyes.
