1483: white noise Jan 3, 2019

Sounds don't have colors objectively tied to them in anyway, yet we still use the term 'white noise'. The term white noise comes from the association to white light, which contains all frequencies of the spectrum of light in equal amounts as to appear white. With white noise machines, the frequencies all use the same intensity, the sounds don't have to be anything recorded in particular, even if the associations are with natural sounds perhaps. This is why there aren't any other types of noise that 'white noise' overtly disambiguates itself from, despite the use of the adjective.
