white noise
White noise has a spectral frequency of 1. Equal proportions of all frequencies are present. Because our ears are sensitive to high frequencies, white noise sounds very "hissy".

pink noise
Pink noise has a spectral frequency of 1/f and is the most natural sounding of the noises. It has a fractal-like nature.

brown noise
Brown noise has a spectral frequency of 1/f^2. There are many more low-frequency components resulting in thunder- and waterfall-like sounds.

Mix 'em, mash 'em, scratch 'em. If you do something cool with these noise files, please let me know. I'd love to hear about it.
