There are a few noises determined by ‘color’ !
White noise represents all the frequencies that we can hear equally. This makes it very useful to ‘mask’ background noises but it’s not very pleasant for the human ear as the high frequencies are more disturbing for us than low frequencies.
Pink noise, also includes all frequencies that the human ear can notice but the lower frequencies are amplified and higher frequencies are lowered, we experience pink noise as soothing. It’s highly recommended for good sleep as it reduces the audible peak levels from a honking car, slamming door etc. Pink noise sounds like a steady rain, rustling leaves, very comfortable.
Brown noise, this noise contains all frequencies but the lower frequencies (bass) are highly amplified. It’s a bit rougher than pink noise, sounds like the roar of a river or a strong wind. It’s used for relaxation, focus, and sleep improvement.
Blue noise, this noise has amplified high frequencies, it sounds like high pitched hissing sound without any bass sounds. It’s mainly used in audio applications for dithering.

Deep sleep, the part of sleep that gives you a powerful feeling once you wake up tends to be prolonged when sleeping with pink noise in the background. Deep sleep also supports a healthy memory.
