It is commonly taught in art schools that certain colors give more advancing and expanding look than the others. However, this observation remains anecdotal and needs to be verified with quantitative methods. We did a quantitative measure of the advancing /receding and the expansion/constriction nature of colors in this study. Fifteen color samples (5 hues by 3 luminance levels) were used as the test stimuli. The order of advance-ness and expanded-ness of these samples was determined by the paired comparison scale. Our results indicate that: (1) The feel of advancing /receding of a color is determined by its hue and luminance. The more a hue moves towards the warm end (long wavelength) and the higher its luminance, the more advancing it appears. (2) The feel of expansion cannot be predicted by a color’s hue and luminance as precisely as in the case of advance-ness. Overall speaking, luminance shows greater contribution than hue in determining our feel of expansion.
