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.

Famous quotes containing the words colors of, colors and/or noise:
“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)
“Few colors last; with their eternal thirst, time and light suck on them, and they bleach the black doctor’s hat until it’s grey like a dunce’s cap.”
—Franz Grillparzer (1791–1872)
“I wonder about the trees.
Why do we wish to bear
Forever the noise of these
More than another noise
So close to our dwelling place?”
