Orange Noise

Orange noise is a variation of white noise where frequencies that are musically dissonant — particularly those that create a "beating" effect — have been removed. The result is a smoother, warmer, more harmonically pleasant noise that some musicians and audio engineers find less abrasive than standard white noise.

It's a relatively niche noise type but has a dedicated following among musicians, music producers, and people who are particularly sensitive to dissonant frequencies. If you've always found white noise slightly "wrong-feeling" or irritating, orange noise removes the specific frequencies responsible.
