Paper Abstract

The viewing conditions in different types of display, such as reflection-copy and cathode-ray tubes, affect the appearance of colors; these effects must be allowed for in designing signals intended to produce color images. A model of color vision has been devised to predict the appearance of colors in different viewing conditions, in terms of their hues, brightnesses, lightnesses, colorfulnesses, saturations, and chromas. The model has been tested by comparing its predictions to published color appearance data. These data include magnitude scaling of the hue, lightness, brightness, and colorfulness of colors displayed as reflection samples, on cathode-ray tubes, on projected slides, and on transparencies viewed on light boxes. On the whole, the predictions given by the model compare reasonably well with the precision with which color appearance data can be determined.
