When I was a kid, my pony's (Mischief) colors were black and white. I even had a black and white lead rope. She was a bay, so the black looked really great with her black mane and points and she had one white boot, so it picked that up. Only thing thing that wasn't black and white was my brush box, which was pink. :)
No horse right now, but when I get one...hopefully in about a year if everything goes according to plan...I can't wait to pick out a cool color scheme. :) Thinking I might avoid pink...it seems to be a super popular color!
