Even dark colored eyes often don't have the same color throughout- but with darker colors, a slight difference doesn't show up because there's less contrast. You have pretty eyes! I have dark brown eyes, and my eye color gets darker as it nars the iris, too.
That's been recently amended a few years ago. There are now 3 genes that dictate eye color. 2 of the gene pairs occur on chromosome pair 15, 1 occurs on chromosome pair 19. The bey 2 gene, on chromosome 15, has a brown and a blue allele. A second gene, located on chromosome 19 (the gey gene) has a blue and a green allele. A third gene, bey 1, located on chromosome 15, is a central brown eye color gene.
It's funny, as advanced as we are, there's still lots of things still to be discovered about the human body and genetics.
Eye color can also change with age (also disease and injury). It can become lighter or darker with age, and change from brown to grey or blue to hazel, etc.
