Nobody has my color, where did it come from?

Answer 1

Nobody has your color because your color is all those combined!

Answer 2

eye color is a very complicated trait. it could come from very distant ancestors and can be mixed between relatives as well.

Answer 3

"We used to think of brown being "dominant" and blue being "recessive." But modern science has shown that eye color is not at all that simple. Also, eye colors don't come out as a blend of the parents' colors, as in mixing paint. Each parent has two pairs of genes on each chromosome. So multiple possibilities exist, depending on how the "Wheel of Fortune" spins."
