Colorimeters Colorimeters: 1. Visual instruments in which the amounts of three primary lights that match a test color when additively mixed are determined and provide a measure (the tristimulus values) of the test color. 2. Visual or photoelectric instruments for measuring color using (usually) three filters with broad spectral bands. 3. In chemistry, a color comparator used to determine the concentration of absorbing species by Beer's law.
