E-2-4 基本6色の時間的色彩系列による人間の色彩感覚の分析(色彩認識)

抄録

We examine how an expanded type sequence on plane of the six fundamental colors affects human color impression. In order to investigate the different effects of two spatial sequences, we consider a hexagonal diagram that is a projection of RGB color space from white to black. The hexagonal diagram corresponds roughly to the hue circle indicated by both hue and saturation in the HLS system. The projected route area indicates the magnitude of naturalness (as in rainbows) for color sequences. The minimum sequence is similar to the order of colors in rainbows, whereas the non-minimum sequence is completely different. We clarified that subjects of nearly all ages have natural impressions when the route area is large and unnatural impressions when the route area is small.
