How many Caucasian (White people) out of the world actually have brown eyes?
Most of them are brown, but that depends on what you characterize as “white”. Many people that you may not normally think of as white (such as many people of Mexican descent) actually are. In my family, I have blue eyes. My wife and one daughter have hazel eyes, and the other daughter has green eyes. I guess the incidence of various eye colors occurring in a particular area depends upon the genetic traits of those who have settled there and how closely related members of the local population are.
