Color order systems are arranged following certain rules based on human color perception, color stimuli, or object colors, and have been developed for communication. In this paper, the historical background of the color order system will be discussed, and the mechanism of primary colors, full colors (pure colors), and complementary colors (opposite colors) will be compared. The color wheel is not only a simple round chart of the colors of the rainbow but also helps to explain physiological perception such as complementary afterimages. The three attributes (hue, value, and chroma) and color solid made common by the Munsell color system and the systems used in Japan will also be reviewed.
