The idea in one line: a 'noise color' just describes how sound energy is spread across frequencies. Shift the balance toward the bass and you get brown; toward the treble and you get blue. Same random hiss, different tilt - and a very different feel.
What a noise color means
All these noises are random sound containing many frequencies at once. What changes between colors is the balance: how much energy sits in the lows versus the highs. That balance completely changes the character - from a deep rumble to a bright hiss.
The main colors
Flat and even - bright, like static. The strongest all-round masker.
Softer highs - warm and rain-like. Studied for deeper sleep.
Bass-heavy - a deep, grounding rumble. Gentle for hours.
Tuned to sound even to the human ear - balanced and neutral.
Brighter highs - crisp and airy, the mirror of pink.
Mid-focused - the natural ambient sound of the outdoors.
Which color should you choose?
For sleep and long listening, warmer colors - brown, pink, gray - are usually most comfortable. For maximum masking of sharp sounds, white is strongest. For focus, many prefer brown or gray. The best way to choose is to hear them.
