Brightness, hue, and saturation have been belived as fundamental dimensions of color perception. The notion has recently been confirmed by empirical evidences using MDS, though a few conflicting results showed itself. The present study was to determine the dimensions underneath the responses of color description with various color names and adjectives, using factor analysis. The rating responses to 77 color patches randomly sampled from Panton Color Book, with 67 predicatives was analysed, appling principal component and Varimax rotation, for each of six observers. The major dimensions coming out from the analysis were not brightness, hue, or saturation. There was a tendency that brightness, hue, and saturation were confused each other into new confounded dimensions such as "Clear-muddiness". "Dark-blueness", and "Dark-brownness". Another tendency was that brightness was devided into "blackness" and "grayness" and hue into "redness", "yellowness", "greenness" and so forth.
