  Color \Col"or\ (k[u^]l"[~e]r), n. [Written also colour.] [OF.
     color, colur, colour, F. couleur, L. color; prob. akin to
     celare to conceal (the color taken as that which covers). See
     1. A property depending on the relations of light to the eye,
        by which individual and specific differences in the hues
        and tints of objects are apprehended in vision; as, gay
        colors; sad colors, etc.
        [1913 Webster]
     Note: The sensation of color depends upon a peculiar function
           of the retina or optic nerve, in consequence of which
           rays of light produce different effects according to
           the length of their waves or undulations, waves of a
           certain length producing the sensation of red, shorter
           waves green, and those still shorter blue, etc. White,
           or ordinary, light consists of waves of various lengths
           so blended as to produce no effect of color, and the
           color of objects depends upon their power to absorb or
           reflect a greater or less proportion of the rays which
           fall upon them.
           [1913 Webster]
     2. Any hue distinguished from white or black.

              They had let down the boat into the sea, under color
              as though they would have cast anchors out of the

        called fundamental colors.
     Subjective color or Accidental color, a false or spurious
        color seen in some instances, owing to the persistence of
        the luminous impression upon the retina, and a gradual
        change of its character, as where a wheel perfectly white,
        and with a circumference regularly subdivided, is made to
        revolve rapidly over a dark object, the teeth of the wheel
        appear to the eye of different shades of color varying
        with the rapidity of rotation. See Accidental colors,
        under Accidental.
