Colors Of Noise
While noise is by definition derived from a random signal, it can have different characteristic statistical properties corresponding to different mappings from a source of randomness to the concrete noise. Spectral density (power distribution in the frequency spectrum) is such a property, which can be used to distinguish different types of noise. This classification by spectral density is given "color" terminology, with different types named after different colors, and is common in different disciplines where noise is an important factor (like acoustics, electrical engineering, and physics). However, different fields may use the terminology with different degrees of specificity.

“Then, bringing me the joy we feel when wee see a work by our favorite painter which differs from any other that we know, or if we are led before a painting of which we have until then only seen a pencil sketch, if a musical piece heard only on the piano appears before us clothed in the colors of the orchestra, my grandfather called me the [hawthorn] hedge at Tansonville, saying, “You who are so fond of hawthorns, look at this pink thorn, isn’t it lovely?””
—Marcel Proust (1871–1922)
“Thought maps existence; fantasy colors it.”
—Mason Cooley (b. 1927)
“I throw myself down in my chamber, and I call in, and invite God, and his Angels thither, and when they are there, I neglect God and his Angels, for the noise of a fly, for the rattling of a coach, for the whining of a door.”
—John Donne (c. 1572–1631)
