Abstract
It is important to investigate color difference in two directions of microscopic evaluation and macroscopic evaluation. In the microscopic evaluation, effects of Munsell chroma and Munsell value on hue discrimination thretholds had been investigated systematically.
Continuously, problem of color difference has been dealt with macroscopic evaluation. Color samples having Munsell value and chroma 6/8 were selected 20 kinds and all combinations of 2 color were prepared on ad jacent condition. Construction of space in the color difference based on their date after judgment of color difference were tried, using the method of eijzrtype quantification.
Configuration of colors on the color difference arrange in order red, yellow, green, blue and purple as hue circle. Relation between color different space on microscopic evaluation and macroscopic evaluation show results similar. Two color difference formulas CIE 1976 (L*a*b*) and CIE 1976 (L*u*v*) agree most with psychological scale obtained on macroscopic evaluation.
