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:
“Painting seems to be to the eye what dancing is to the limbs. When that has educated the frame to self-possession, to nimbleness, to grace, the steps of the dancing-master are better forgotten; so painting teaches me the splendor of color and the expression of form, and as I see many pictures and higher genius in the art, I see the boundless opulence of the pencil, the indifferency in which the artist stands free to choose out of the possible forms.”
—Ralph Waldo Emerson (1803–1882)
“Housekeeping is not beautiful; it cheers and raises neither the husband, the wife, nor the child; neither the host nor the guest; it oppresses women. A house kept to the end of prudence is laborious without joy; a house kept to the end of display is impossible to all but a few women, and their success is dearly bought.”
—Ralph Waldo Emerson (1803–1882)
