Abstract: A color displaying method comprises determining the CIE (Commission Internationale d'Eclairage) tristimulus values of a desired color to be displayed. The tristimulus values are converted into corresponding electrical signals in accordance with the relative luminance value of the source of radiations employed to produce the desired color. A system for displaying colors is also disclosed which includes an electro-optical color imaging device. The tristimulus values of the desired color are generated in a computer in response to a set of numerical data keyed through a data input device. The tristimulus values are converted into corresponding electrical signals which are then corrected in amplitude in accordance with the emission characteristics of the imaging device. The latter is driven in response to the amplitude-corrected electrical signals to produce the desired color.
