Analysis of Color Combinations in the Heian Period, “Kasane-Irome”, by using Color Affection Prediction Formulas

Abstract

To identify the characteristics of the two-color combinations called “Kasane-Irome” which are found in the noble attire of the Heian Period, we calculated their estimated values of the affection factors by using color affection prediction formulas and compared them with the values calculated for two-color combinations of 201 colors of Practical Color Co-ordinate System (PCCS). The result showed that in 120 types of “Kasane-Irome”, the average value of the “contrast” factor was lower and those of the “floridness” and “warmth” factors were higher as compared with the values of 20100 two-color combinations of PCCS 201 colors. However, there was no statistically significant difference found in the average value of the “pleasantness” factor that shows degree of good harmony. There was no statistically significant difference in the average values of the factors such as “pleasantness” “contrast” “floridness” and “warmth” which are caused by “Kasane-Irome” used in different seasons.
