The Sisters' Book Of Randomness

An idea

So...im thinking about doing something for when school starts. I would make bracelets with three different colors. For this to work, i need three bracelets

Pink white purple
Red orange blue
Black red pink

So, people would have to look for someone who has a similar color, and try to become friends with them. If they end up not liking each other, that is why there are two colors to choose from.

Is this idea dumb or reasonable?
