Spectral Color - Non-spectral Colors

Non-spectral Colors

Among some of the colors that are not spectral colors are:

  • Grayscale (achromatic) colors, such as white, gray, and black
  • Any color obtained by mixing a gray-scale color and yet another color (either spectral one or not spectral), such as pink, which is a mixture of a reddish color and white.
  • Purple colors, which in color theory also include magenta colors, rose colors, and other colors on the line of purples, which are various mixtures of violet and red light.

Famous quotes containing the word colors:

    “One wonders that the tithing-men and fathers of the town are not out to see what the trees mean by their high colors and exuberance of spirits, fearing that some mischief is brewing. I do not see what the Puritans did at this season, when the maples blaze out in scarlet. They certainly could not have worshiped in groves then. Perhaps that is what they built meeting-houses and fenced them round with horse-sheds for.”
    —Henry David Thoreau (1817–1862)
