The use of color in coding displays
Abstract
The objectives of this study were to (a) determine the maximum number of absolutely identifiable hues, (b) construct an "equal-discriminability" scale of hues, and (c) to validate the scale on an independent population sample. Surface colors from the Munsell fifty-hue series of colored paper provided the stimulus material. Results indicate that for practical coding purposes a maximum of five to eight colors can be used, with the exact number depending on the viewing condition and the proportion of the population that must read the code without error. Advantages and disadvantages of color in coding are discussed; current engineering practice is reviewed. A color plate gives examples of 8, 7, 6, and 5- category codes. Specifications for these codes are given in the text.
