Color Display Spectrum
Color displays (e.g., computer monitors and televisions) mix red, green, and blue color to create colors within their respective color triangles, and so can only approximately represent spectral colors, which are in general outside any color triangle.
Colors outside the color gamut of the display device result in negative values. If color accurate reproduction of the spectrum is desired, negative values can be avoided by rendering the spectra on a gray background. This gives an accurate simulation of looking at a spectrum on a gray background.

—Norman Mailer (b. 1923)
“Nobody thanks a witty man for politeness when he accommodates himself to a society in which it is not polite to display wit.”
