Sound masking is the addition of natural or artificial sound into an environment to cover up unwanted sounds. At an appropriate audio level, sound masking noise can help to reduce or eliminate the sound of misophonia triggers. The color of noise is determined by a broad characteristic of its power spectrum. But what's important to know is which color sound will work for you in a specific situation. In very simple terms, you could think of white noise as a hiss, pink noise as a buzz, and brown noise as a roar.
