Noise colors, compared

The color names describe how energy is distributed across frequency. They are useful technical shorthand—not a ranking of which sound is best.

Choose by comfort, not hype

Start at a low volume and compare each color for a minute or two. White noise may mask higher-frequency detail more strongly, while pink and brown reduce high-frequency energy progressively. Speaker size, room acoustics, and your own hearing all change the result.

Tune without jargon

The player’s Warmer/Bright and Deep/Light controls adjust a small filter chain after generation. They let you adapt a noise color to your device without pretending that one fixed spectrum works everywhere.
