So I have a question about my ethnicity?

The colour of your eyes says absolutely nothing whatever about your ethnicity. Most of us are "of mixed race" these days . The only race that really matters is the human race. There is less gentic difference between Hilary Clinton and Nelson Mandela than there is between one tribe of Bonobo Chimpanzees and another. We're talking tiny fractions of 1%. Don't worry about what you are. You are just a human being like the rest of us.
