Yikes. What terrible branding!

"Green noise" is better, sort of honest, and obvious.

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.
