DIMENSIONS OF COLOR SENSATION

Weckroth, J. Dimensions of color sensation. Scand. J. Psychol., 1961, 2, 65–70.—The investigation is based on a dimensional (similarity) analysis of color sensation by Ekman (1954). It was assumed that the factor loadings of the three first factors extracted in this analysis would correspond to the proportions of blue, green, and red required, when these colors are mixed to match different wave lengths in the spectrum. This assumption was supported by the results. The coefficient of correlation between the two sets of values was 0.973, which indicates good, although not perfect, agreement.
