The basics of color science are described from the viewpoints of optics, psychophysics, and colorimetry. First, the three elements of color creation are introduced and the fact that color is a perception reflecting spectral information mediated by light is confirmed. Then, the relationship between spectral distribution and attributes (hue, saturation, lightness) is considered. Color order systems and colorimetry are introduced by discussing the color vision trichromacy. In addition, through the concept of metamerism, the principles and problems of color rendering devices are discussed. In the latter half of the paper, various color vision phenomena are introduced, and their mechanisms and functions are described. Finally, some ideas and applications related to color vision characteristics and color vision diversity are introduced.
