pre-order the membershipBoth are noise: every pitch at once, at random. Pink noise loses a little loudness as it climbs, so each octave carries about the same energy; it sounds even, bright at the top. Brown noise falls off twice as steeply, so the low end is much louder than the high; it sounds darker, rounder, closer to a rumble.
Here both come from the same engine and the same seed: today's moon, wind and quakes shape the breath of the sound, and only the colour changes when you switch. The machine keeps the one you pick, with a timer and the other colours.
