what are they?

Just as our ability to perceive light distinguishes between colors like green and violet, colored noise operates similarly. Different types of noise are categorized by color according to their frequency spectrum, reflecting how we respond to varying frequencies. 

They are often used to mask distracting sounds, which can support sleep or concentration. 

Wellness affects

The color noise spectrum is used in various wellness-related contexts. 

Brown Noise: mimics the sound of the womb, and is the most bass-heavy

• Sounds like: waterfalls, crashing waves, strong winds, and rumbling thunder
• Use for: deep, soothing relaxation, gentle concentration while reading, or to reduce anxiety

Pink Noise: considered a softer, more natural version of white noise with its lower frequencies

• Sound like: steady light rain, gentle wind, calm waves, and rustling leaves
• Use for: sleep, provides a calming and familiar background

Green Noise: nature's background noise, and emphasizes mid-range frequencies 

• Sounds like: rainforest ambiance of birds chirping, leaves rustling, distant waterfalls, streams, and animal calls (mid-range audio)
• Use for: relaxation and meditation, it creates a calm atmosphere with a hum similar to natural environments

• Suggested affects seem to vary online. So rather than assume the use based on how we've categorized them, try actually listening to each color noise and observing how your unique body responds to each. 
• We have not included white noise as some suggest it can stress the inner ear and damage our hearing, while conversely others suggest it can help people with tinnitus (chronic ringing in the ears). It's also been noted that it may stunt physiological and social development in children, particularly when over 60 decibels and for extended periods of time (though that could be said for any sound). 
• The three color noises we have included are known to more closely mimic sounds found in nature, offering a more gentle frequency.
