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.

Famous quotes containing the words color and/or display:
“But whenever the roof came white
The head in the dark below
Was a shade less the color of night,
A shade more the color of snow.”
—Robert Frost (1874–1963)
“We rarely quote nowadays to appeal to authority ... though we quote sometimes to display our sapience and erudition. Some authors we quote against. Some we quote not at all, offering them our scrupulous avoidance, and so make them part of our “white mythology.” Other authors we constantly invoke, chanting their names in cerebral rituals of propitiation or ancestor worship.”
—Ihab Hassan (b. 1925)
