When you think of noise, do you think of a color that associates with it? The phrase “colors of noise” is a fun way to describe noises and helps you remember their different characteristics. Each type of noise has a unique frequency that you can use to help you relax, focus and even sleep better! Keep reading and we’ll discuss the uses of the colors of noise.

What is Noise?
Noise can be a real nuisance, whether it’s from a construction site or an electronic device. Noise is basically any sound that gets in the way of what we really want to hear. They have different intensities, frequencies, and durations and can come from machines, traffic jams or even tornadoes! We can measure noise in several ways, like with sound level meters or spectrum analyzers.
Colors of Noise
White Noise
White noise is basically like a radio station limbo. Somewhere between stations, hearing the same static-y sound no matter which frequency you tune into. It’s strangely soothing and you can use it in several ways. If your neighbor’s been cranking their music up late at night, white noise could help drown it out so that everyone gets some much-needed rest! Plus, researchers say babies love listening to this kind of background buzz. Play white noise for your kiddo to help them focus while they play, study, or work.
Pink Noise
Pink noise is similar to white noise but with a twist – equal power in each octave makes it sound different, almost like the pitter-patter of rain or rustling leaves! This makes pink noise great for all sorts of uses. Whether it’s music production, masking background chatter or helping people sleep. Yeah, you can call it nature’s sleeping pill if you want – now that’s sweet dreams made easy!
Colors of Noise: Brown Noise
Brown noise, also known as Brownian noise, is the deep rumble of thunder, like what you hear when a storm’s brewing! It has more low frequency than pink and less high frequency, earning it its name after botanist Robert Brown. While it’s not the most popular color of noise like white or brown noise, people use this random walk-type sound for audio production to make special effects! It’s also a great sleep aid if you’re struggling to nod off at night. Or to mask other sounds in your environment. Brown noise can also act like an audiophile stress test on speakers to identify any issues with their response in the lower ranges.
Blue Noise
Blue noise is like a high-pitched whistle you might hear in the distance. It’s not as popular as other types of ‘noise’ such as white, pink or brown but it has its purpose! It’s the opposite of brown noise, meaning it’s mostly treble with no bass. Blue noise can test audio equipment and speakers to make sure they sound pristine – even at higher frequencies. Blue noise isn’t good for helping you fall asleep or focus.
Violet Noise
Violet noise, also known as purple noise, is like a high-pitched hiss. Think of it as the sassy older sister to blue noise! People typically use this color of noise in more specialized applications like audio production and digital image processing. It helps people identify issues with higher frequency responses for an even better sound. Those with tinnitus enjoy the benefits of violet noise as it masks the high-frequency noises they experience.

Grey Noise
Grey noise sounds like a weird mix of white and pink noises. It’s not as popular for everyday uses, but it does have its place in the world! Audio production professionals love to use grey noise because it can help identify any issues with high-frequency responses when testing audio equipment or speakers. It’s another frequency that people with tinnitus enjoy because it masks high frequencies.

Benefits of Different Colors of Noise
Different colors of noise can provide distinct benefits depending on what you’re trying to achieve.

If you can’t fall asleep, try swapping that white noise app for one with calming blue tones.
