"Color is the son of light, and light is the mother of color", "There is colorless light in the world, but there is no dim color". These famous conclusions about light and color fully illustrate the dependence of color on light and the inseparable characteristics between them. In photography practice, from a technical point of view, exposure plays a decisive role in the success or failure of photography. It is of great practical significance for the correct restoration and accurate reproduction of colors in contrast films and the creative expression of colors.

In the specific shooting process, there are many factors that affect the color, many of which are beyond the photographer's control and interference, such as the direction and intensity of sunlight, the environment around the subject, the roughness or smoothness of the subject's surface and so on. When other conditions cannot be changed artificially, exposure becomes the decisive factor of color. In order to truly understand the formation of color, the analysis of color is essential. The introduction of color theory in some photography books is either superficial, too difficult or even wrong, which intentionally or unintentionally misleads photographers. When we talk about color, we can't help but involve three attributes of color. There are countless colors in the world, but any color (except black, white and gray) has three attributes: hue, lightness and purity.
