Two approaches to color measurement are presented, the spectrophotometer and the reflectometer. Descriptions are given of two portable instruments, one of each type. The first instrument was built using a flashlight lamp as light source, a wedge interference filter as monochrometer, and a cadmium sulphide photoresistor as a detector. The second instrument was built with three filters which provided the tristimulus curves of the CIE standard observer, a flashlight lamp, and three barrier layer cells as detectors. (Author).
