To investigate the best color gamut for color reproduction including reddish objects from KANSEI evaluation point of view, subjective evaluation experiment using five adjective pairs was conducted in the conditions of wide gamuts with four different red primaries from 610nm to 640nm. Two sets of 15 color images that were made for sRGB, were used as test stimuli of Group 1 and Group 2. Seven images selected from the ITE Ultra-high definition/wide-colorgamut (UHD/WCG) standard test images were employed as test stimuli of Group 3. The red primaries of 630nm and 640nm provides deep color and impressive feeling, but the most unnatural. Gender difference was observed in the evaluations of beautifulness and likability in the Group 3, suggesting that deep red is not necessarily preferred by female observers.
