Noise colour comparison
White, pink and brown noise are the same random signal shaped by different spectral slopes. Switch between them and the difference is obvious within a second.
Evidence rating: Established science
Nothing playing.
Small laptop speakers roll off the bass, which makes brown noise sound thinner than it is. Headphones or a full-range speaker give a fairer comparison.
Noise colour is a description of a signal's spectrum, not a claim about its effect on you. People differ in which colour they find least intrusive; there is no single correct answer.
