Snap Magazine: How'd you get a job painting bikes if you're color blind?Brian Foster: (laughter)Side note: I don't think they knew.

The only time I ran into trouble was late at night when I was by myself and there was no purple paint--I just mixed some blue and some red and see what I came up with (more laughter).
