COLOR FROM THE METEOROLOGICAL STANDPOINT,

Abstract

The principal types of instrument for measuring colors are defined in terms of the three trisimulus values X, Y, Z. They are: the spectrophotometer, the visual or photoelectric colorimeter, direct or differential measuring in struments and devices for comparing adjacent colors. All have three separate elements in common: light source, optical system and measuring device. Four criteria are defined for assessing the degree of accuracy of each type. It is shown that a choice must be made of a principle for measuring the modifying factor m and the type of apparatus to be used. This choice will be determined by the nature of the colorimetric problem involved. (Author)
