Primary colors
(gcide) | 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
Helmet.]
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]

Complementary color, one of two colors so related to each

primary colors, in consequence of partial absorption.

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.
