this was oddly uninformative and misinformative. the names for white and pink noise are related to light but brown noise is named after robert brown.

white noise is equal power (amplitude/"volume") across frequencies (1/1), pink noise equal power per octave (1/frequency), and brown/red noise is -6dB/octave (1/frequency^2). there is also grey noise, blue noise, black noise, violet noise, and others. and no mention of the fletcher-munson curve (how sensitive our ears are across the frequency spectrum).
