Blue noise's power density increases = 3.01 dB per octave with increasing frequency (density proportional to f ) over a finite frequency range. [5] In computer graphics, the term "blue noise" is sometimes used more loosely as any noise with minimal low frequency components and no concentrated spikes in energy.
Under the influence of hashish, he described: "My hearing was developed extraordinarily; I heard the noise of colors. Green, red, blue, yellow sounds reached me in perfectly distinguishable waves". [21] Gautier made a sketch of Gustave Moreau playing the piano, where he depicted his chromesthetic experiences as lines of color above the ...
"The term 'color' of noise is used to describe the strength and frequency of a noise signal on the power spectrum," Shelby Harris, Psy.D., a clinical psychologist specializing in behavioral sleep ...
Hearing thresholds of humans and other mammals can be found with behavioural hearing tests or physiological tests used in audiometry. For adults, a behavioural hearing test involves a tester who presents tones at specific frequencies and intensities . When the testee hears the sound he or she responds (e.g., by raising a hand or pressing a button.

The same line of reasoning can be applied for blue light/noise (a domination of high frequency contents) and for black light/noise (absense of energy throughout the whole frequency range, which does not seem as much of a "help" for visualising the nature of the noise - it is kind of obvious anyway).
