They are engineering terms, not marketing terms. The 'colors' are to give you an analogy of sound frequencies in the spectrum: White is a blend of all (audio) frequencies with equal intensities; with pink noise, the intensity falls off at higher frequencies (1/f), and with brown noise the intensity falls off faster at higher frequencies (1/f^2).

Yep. More detail (with samples) here: http://en.wikipedia.org/wiki/Colors_of_noise

Sorry, I actually knew that -- I spent a few years of my life building production studios and doing audible spectrum tests.

Cheap humor though, I apologize.
