My biking helmet is bright yellow. Anything that will help in any tiny way to help cars see me better is the right color for me.
On the other hand, my roller skating helmet is black. Not much chance of getting hit by a car in the roller rink! Besides, the rink floor is white, so black stands out anyway. In the rink, little kids are going to fall across your path no matter what you wear. So....bike wear=visibility, roller rink wear=padding.

With my figure, there is never any doubt that I am a 'girl'....no need to clarify it with pink like they do with babies so you can tell what sex they are.
