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.

“How comes it that you curse, Frere Jean? It’s only, said the monk, in order to embellish my language. They are the colors of Ciceronian rhetoric.”
—François Rabelais (1494–1553)

Fallen is at length
Its tower of strength;
Its sun is dimmed ere it had nooned;
Dead lies the great Ahkoond,
The great Ahkoond of Swat
Is not!”
