Really? Wow that sounds very rare. And I thought David Bowie's green/blue was cool. |

Do mixed Korean/Western babies always have brown eyes?
Ever seen a 1/2 Korean with blue or green eyes? |
Hmm. There is a (I think she's from Japan,not sure) runway model that is half asian and half white and she has green-blue eyes. Tyra Banks has hazel eyes, and both of her parents are black, but I have no idea about her grandparents.
I copied this off a medical forum:
For eye color, everyone appears to miss a main point. There is no such thing as blue eyes, there is only brown.
As a doctor, who looks through a slit lamp biomicroscope at eyes all day long, this is very obvious. By this, I mean that there is no blue pigment, or green pigment... there is just brown.
The color of the eye is a result of two components, the color of deeper tissue layers of the iris, and the amount of melanin granules that lay within the surface layers.
The exception to this, are albinos. Because an albino's deep layers have no pigment, their eye color is a combination of white tissue and the red fine blood vessels that lace the iris... without magnification, the lace of red and white combine to look pink. Now for everyone else---> In everyone else, the anatomy of the iris is such that the deeper layers are much the same color.
If that were the sole determinant of eye color, then everyone would have blue eyes (I'd have to go back to my ocular anatomy books to be specific, but there is no blue color... but, the combination of a pigmented layer, a non-pigmented layer, and blood vessels all refracting thru semi-translucent tissue provides a blue color. It's analogous to the blue sky... there's no blue pigment in the sky, but refraction of light in the atmosphere leaves it that color... accept in Los Angeles).
In any case, we know that everyone's eyes are not blue, and that is because the amount of melanin pigments granules that are embedded in and on the surface layer of the iris varies. How much melanin varies from person to person.
It is the same melanin that pigments our skin, so that is why people with a light complexion, tend to have blue eyes (Swedes), and why people with dark complexion, tend to have dark eyes (Africans). In general, if you inherit a lot of melanin (say 7 on a scale of 7) you will have dark brown eyes, if you inherit a bit less melanin (say 6), you'll have light brown eyes, inherit a level 5 degree and your eyes will be hazel, 4 is green, 3 is dark blue, 2 is light blue, and 1 is very light blue...
It is really a continuum. It is not a strict blue-green-brown, but a continuum dependent on how many pigment granules you inherited and then expressed... really there are thousands of pigment granules on the face of the iris, and a person who has 10,845 granules will have a slightly darker eye than the person who has 10,456 granules.
Also, the pigment granules can vary their distribution on the face of the iris, so you can have streaks of color (blue showing thru in some areas) or pigment clumps (freckles, birth marks)... a variance called heterochromia of the iris, or the there may be a difference between the eyes where one eye has a little more pigment (heterochromia of the iridies). I have one more observation: In literature, I read that brown eyes are "dominant".
I do not see this as an absolute.... Instead, when a brown-eyed person and blue-eyed person has a child the child will have a contribution of the mother and fathers' genes, so they will tend to have a moderate amount of pigment on the face of the iris (less than the brown-eyed parent, and more than the blue-eyed parent), but a moderate amount of brown pigment is overpowering, thus a light brown eye.
Bottom line, since their are a number of locations on genes that govern how much pigment is passed to the child, there will be variation in the lump sum of melanin granules that are imbedded in the surface layer of the iris... if you get a lot of granules, you will have brown eyes.... if you only get a smaller portion, you will have blue eyes. But, it is possible for blue-eyed parents to combine to create a genetic sum that results in brown-eyed children... and visa versa.
If you want to get a feel for eye color... go to an eye doctor's office, and ask to look through a slit lamp at two friends' eyes (one friend with blue eyes, the other with brown) ....you will see fine pigment granules on the iris of both... just one has more granules than the other. |

Oh, yeah, and we're all black, because we all have melanin.
That article makes for good discussion, but it makes me feel a bit to interested in singing, "Kum-baya" or "We Shall Overcome" than to ignore the fact that I see color in peoples' eyes.
That guy may as well tell us that all people are red-blooded, or that all basic human cells follow the same colors across racial boundaries.
We already know this. |
