Accidental color
(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]
2. Any hue distinguished from white or black.
[1913 Webster]
3. The hue or color characteristic of good health and

semblance; excuse; disguise; appearance.
[1913 Webster]

6. Shade or variety of character; kind; species.
[1913 Webster]
Boys and women are for the most part cattle of this
color. --Shak.
[1913 Webster]
7. A distinguishing badge, as a flag or similar symbol
(usually in the plural); as, the colors or color of a ship
or regiment; the colors of a race horse (that is, of the
cap and jacket worn by the jockey).

In the United States each regiment of infantry and
artillery has two colors, one national and one
regimental. --Farrow.

[1913 Webster]
Body color. See under Body.
Color blindness, total or partial inability to distinguish
or recognize colors. See Daltonism.
Complementary color, one of two colors so related to each
other that when blended together they produce white light;
-- so called because each color makes up to the other what
it lacks to make it white. Artificial or pigment colors,
when mixed, produce effects differing from those of the
primary colors, in consequence of partial absorption.
Of color (as persons, races, etc.), not of the white race;
-- commonly meaning, esp. in the United States, of negro
blood, pure or mixed.
Primary colors, those developed from the solar beam by the
prism, viz., red, orange, yellow, green, blue, indigo, and
violet, which are reduced by some authors to three, --
red, green, and violet-blue. These three are sometimes
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.

contemplation of actually colored bodies.
Accidental point (Persp.), the point in which a right line,
drawn from the eye, parallel to a given right line, cuts

[1913 Webster]
Syn: Casual; fortuitous; contingent; occasional;
adventitious.
Usage: Accidental, Incidental, Casual, Fortuitous,
Contingent. We speak of a thing as accidental when
it falls out as by chance, and not in the regular
course of things; as, an accidental meeting, an
accidental advantage, etc. We call a thing incidental
when it falls, as it were, into some regular course of
things, but is secondary, and forms no essential part
thereof; as, an incremental remark, an incidental
evil, an incidental benefit. We speak of a thing as
casual, when it falls out or happens, as it were, by
mere chance, without being prearranged or
premeditated; as, a casual remark or encounter; a
casual observer. An idea of the unimportant is
attached to what is casual. Fortuitous is applied to
what occurs without any known cause, and in opposition
to what has been foreseen; as, a fortuitous concourse
of atoms. We call a thing contingent when it is such
that, considered in itself, it may or may not happen,
but is dependent for its existence on something else;
as, the time of my coming will be contingent on
intelligence yet to be received.
