Well, nothing better to do tonight than read twelve pages of eye color, so here is my contribution:
My av is a true picture of my eyes, but they are rarely that light and clear. Lighting conditions, clothing, make up, and mood will make them appear
a different color ranging from almost clear to dark blue/violet. The reason that emotions will change eye color is because emotions change pupil
size, either compressing or spreading out the pigmentation of the iris.
I am very interested in genetics and try to read and understand as much as possible on the subject. It is my understanding that eye color cannot be
determined by the Punnett square because it is not dependent on only one gene. Therefore any set of parents can have any range of eye color in
children. Though blue eyes are less prevelant than brown, it cannot be said that blue eyes are dependent on a strictly recessive pair of genes from
two parents. Eye color is also not only dependent on melanin production. It also has to do with cellular density in the iris.
No one eye color is actually better than another. For instance light eyes have a higher chance of melanoma while darker eyes have a higher instance
of cataracts. But I do remember reading that something suggesting that blue eyes were more appealing because it was easier to see the contraction and
release of the pupil, making it easier to read the person better.
