The difference in perceived colour caused by placing a colour filter over only a small part of, or over the whole picture area of, a projected slide is used to illustrate the types of measure that are appropriate for evaluating colour appearance in pictures. Psychophysical measures are of limited use, psychometric measures are of more help, but psychoquantitative measures, based on subjective scaling and elaborated on to take account of the effects of absolute luminance levels, are found to be the most appropriate.
