I don't think colour really comes into it with me, it's got more to do with them as person and my attraction to that rather skin colour. None of my friends have any problem dating different races, although alot of the kids at my secondary school found it taboo going for someone not of their own race.
My dad's fine with whatever person I bring home as long they treat me right, my mum's a different story. She's not outwardly racist but was brought up in an environment where you married or had relationships with people of your own race, and even though my dad was brought in the same area in the same generation he's updated his view to current times. I never tell my mum about a guy until it's really serious and girls, well there's no point even breaching it with my mum.
