  Let me think, Genetics?  There are actually Black people with blue eyes like me.  If it makes you feel better, I wear dark brown contacts to cover them (and for my blindness).   And on a good night, If I stare at the moon, they'll turn green.  If your eyes really are naturally blue it is only because you have partial White ancestry. Which you do, you have already said before you are part Irish and I think German as well, that would explain your supposed natural blue eyes wouldn't it now? ;) You are not even a real Congoid, you are a mongrel just like the majority of African-Americans.
