1/f

LIT"Pink noise" has power spectral density ∝ 1/f: equal power per octave. White noise has flat power (equal per hertz), and brown/red noise goes as 1/f². The names borrow from light: white has every frequency equally, and tilting power toward the low end, the "red" end, makes it pink. 1/f fluctuations show up in electronics, heartbeats and music. The colour name is an analogy, not a measured colour.

COMPUTEDGenerated live with Paul Kellet's filtered-noise approximation. The spectrum is estimated with an FFT, and a log-log fit gives the slope. Toggle white, pink or brown, and play it (Web Audio, quiet). Nesting: the spectrum bars coloured as if the frequencies were light, red at the low end, in the void.
