highly chromatic example. The sensation is produced by a pure blue whose chroma has been diminished while its luminosity has been increased. Thus blue and violet are the same color, though the sensations are different. A mere increase of illumination may cause a violet blue to appear violet, with a diminution of apparent chroma. This color, called violet or blue according to the quality of the sensation it excites, is one of the three fundamental colors of Young’s theory. A deep blue tinged with red.
Virdian.—Same as Veronese green.
White.—A color transmitting, and so reflecting to the eye, all the rays of the spectrum, combined in the same proportion as in the impinging light.
Yellow—The color of gold and of light, of wave length 0.581 micron. ‘The name is restricted to highly chromatic and luminous colors. When reduced in chroma, it becomes buff; when reduced in luminosity, a cool brown. See Brown.
Veronese Green.—A pigment consisting of hydrated chromium sesquioxide. It is a clear bluish green of great permanency. Also called Viridian.
