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
