Uh huh, with a hint of green, but they're not hazel.
-
my eyes are green w/ a little blue. they have dark green rings around the edge. my bf says i have, "prettiful eyes."
-
Wow, they seem beautiful. =) I wish I had eyes like that.
-
aww, thanks.
-
wow those do seem pretty =)
-
Your welcome, Kitty.
-
Dark brown.
What, sappi? So everyone with blue eyes shares a common ancestor? But you said it was a mutation, therefore not biological? -
idk how i kno that,so i cant go into much detail
-
Oh okay.

i cant explain but i found this artical online
What is the genetic mutation
“Originally, we all had brown eyesâ€, said Professor Eiberg from the Department of Cellular and Molecular Medicine. “But a genetic mutation affecting the OCA2 gene in our chromosomes resulted in the creation of a “switchâ€, which literally “turned off†the ability to produce brown eyesâ€. The OCA2 gene codes for the so-called P protein, which is involved in the production of melanin, the pigment that gives colour to our hair, eyes and skin. The “switchâ€, which is located in the gene adjacent to OCA2 does not, however, turn off the gene entirely, but rather limits its action to reducing the production of melanin in the iris – effectively “diluting†brown eyes to blue. The switch’s effect on OCA2 is very specific therefore. If the OCA2 gene had been completely destroyed or turned off, human beings would be without melanin in their hair, eyes or skin colour – a condition known as albinism.
Limited genetic variation
Variation in the colour of the eyes from brown to green can all be explained by the amount of melanin in the iris, but blue-eyed individuals only have a small degree of variation in the amount of melanin in their eyes. “From this we can conclude that all blue-eyed individuals are linked to the same ancestor,†says Professor Eiberg. “They have all inherited the same switch at exactly the same spot in their DNA.†Brown-eyed individuals, by contrast, have considerable individual variation in the area of their DNA that controls melanin production.
Professor Eiberg and his team examined mitochondrial DNA and compared the eye colour of blue-eyed individuals in countries as diverse as Jordan, Denmark and Turkey. His findings are the latest in a decade of genetic research, which began in 1996, when Professor Eiberg first implicated the OCA2 gene as being responsible for eye colour.
Nature shuffles our genes
The mutation of brown eyes to blue represents neither a positive nor a negative mutation. It is one of several mutations such as hair colour, baldness, freckles and beauty spots, which neither increases nor reduces a human’s chance of survival. As Professor Eiberg says, “it simply shows that nature is constantly shuffling the human genome, creating a genetic cocktail of human chromosomes and trying out different changes as it does so.†-science daily.com -
My eyes are green.

Thanks, sappi!
-
dark brown, almost black :P
-
Husky eyes,which is really light blue eyes.
-
Mine are sea blue
