I have brown hair, what color is yours?
My hair is auburn, which is a mix between dark brown with red highlights.
That's awesome! Its kinda cool to know how rare red hair/highlights are. Only 1-2% of humans have red hair.
Really? That is amazing. I'm assuming that 1-2% of those people are Irish decent?
Well, its more common in the European ancestry. But I do believe they are also common in the Irish ancestry too!
That is amazing. I wonder if there is any information about certain red hair people and eye colors. 
The only this I know for sure is that lighter eye colors are more common in "gingers" or persons with red/orange hair. The eyes are colored based on the stregth of the stroma in the eyes.
