Visual observations on gloss have identified approximately six types of gloss. To study the interrelations among these a method for the multidimensional scaling of gloss was devised. Two sets of painted specimens were examined. The first set covered a wide range of gloss using specimens that were a single grey color. The second set covered a more restricted range of gloss but consisted of black, grey, and white specimens. The results for these particular specimens under the particular viewing and illuminating conditions described yielded unidimensional interval scales. These interval scales were then correlated with the instrumental measurements obtained from the specimens. Equations relating the visual data to the instrumental data were derived.
