A NOMENCLATURE OF COLORS. 
fixity of the nomenclature is even more necessary than 
its simplification. 1 
As is stated on page 23, had we pigments representing 
the three primary colors in their absolute purity, it would 
be a simple matter to produce all possible modifications 
of color by their combination with one another, together 
with the addition of black or white, when required. Even 
with the imperfect pigments now available, by far the 
larger number can be made (see pages 29-32). 
According to Von Bezold, the term "hue" is synony- 
mous with color ; a " tint " denotes a color or hue modi- 
fied by admixture of white; while a "shade" implies a 
color darkened with black. The same author classifies 
colors as follows : — 
I. Gold, silver, black, and white. 
II. Full colors, or those of the solar spectrum (that is, blue, green, 
and red, — or, as some authorities have it, and especially 
as popularly supposed, blue, yellow, and red). 
III. a. Dark colors, or those shaded with black. Such may be 
properly termed " shades " of blue, green, red, etc. 
b. Light colors (diluted or mixed with white) and pale 
colors (which are still further lightened or diluted). 
c. Broken colors, by which is meant "those colors which 
reach the eye mixed with faint white, that is to say, 
gray light, but in which the specific character of their 
hue is still expressed with tolerable decision. If the 
gray predominates to such an extent that we receive 
only a very slight sensation of color, we speak of a 
gray with the addition of the name of a color, such as 
greenish gray, bluish gray, etc." (pages 97, 98).

supplied.
