Brown, Pink, and Green Noise: Which Color Helps You Sleep?
You've heard of white noise, but what about the rest of the rainbow? Discover how Brown, Pink, and Green noise can mask distractions and soothe your nervous system.
The Colors of Sound
Just as light has colors defined by frequency, sound "colors" are defined by how energy is distributed across the frequency spectrum. Different colors have different effects on the human ear and brain.
White Noise
Equal energy per frequency.
Static, hissing radio. Great for blocking sudden noises but can be harsh.
Pink Noise
Equal energy per octave.
Rain, wind through leaves. Balanced and soothing, arguably the best for sleep stability.
Brown (Red) Noise
Deeper, lower frequencies.
Distant thunder, waterfalls. Rumbly and warm, lacking high-pitched hiss.
Green Noise
Centered around 500Hz.
Running water, nature ambience. Great for feeling connected to the earth.
