| Outline of Final Research Achievements |
Among the RGB primaries of the display, the B primary is affected by optical properties of ocular media such as chromatic abberation, scatter in the eye, and the absorbance of macular pigments. On the other hand, it affects the color appearance of image the most strongly. Therefore, to investigate the best blue primary for color display from KANSEI-evaluation point of view, evaluation experiment using Semantic Differential method was carried out using four different blue primaries of 430nm, 450nm, 470nm, and 480nm. The blue primary of 470nm shows the highest scores for bluish test images. Many points in blue and blue-green images distribute along the unique blue locus in the previous study, suggesting the importance of color appearance in selecting the blue primary.
