How can noises (like white noise) have colors?

Looking at Simply Noise, I am struck that it not only has white noise, which I always assumed was some random colloquial term for background noise, but also pink noise and brown noise.
What makes noise pink? Or brown? White? Is there blue noise? Purple noise? Can I get an entire Crayola box worth of noise?
