Thirty-two observers were invited to take part in a psychophysical experiment. Three hundred and sixty-five color sample were provided in the experiment. Each observer was required to do visual identification to classify 365 color samples into 17 PCCS tones. The results showed that the achromatic color tone remained consistent with those purposed by PCCS. However, 12 chromatic color tones were found to be overlapped. Six chromatic tones were found to be sufficient, including PASTEL, MILD, RICH, DEEP, DUSTY, MUDDY. 1. The boundary of PASTEL ranges between 80 and 100 on lightness axis. 2. The boundary of MILD ranges between 50 and 80 on lightness axis, 25 and 50 on chroma axis. 3. The boundary of RICH ranges between 0 and 80 on lightness axis, 50 and 100 on chroma axis. 4. The boundary of DEEP ranges between 0 and 50 on lightness axis, 25 and 50 on chroma axis. 5. The boundary of DUSTY ranges between 50 and 80 on lightness axis, 0 and 25 on chroma axis. 6. The boundary of MUDDY ranges between 0 and 50 on lightness axis, 0 and 25 on chroma axis. Advisor Committee Wen-yuan Lee - advisor
