Three primary colors of red:

Safflower absorbs yellow, cyan, green, blue and purple in white light, but reflects red light, so it looks red, so the colors people see are different colors reflected by objects that do not absorb or absorb less. When different light colors reflect an object, they will show different colors, and objects that are colorless in the sun will also become colored objects.

Cloth that appears green in the sun will turn black in red light, because green cloth only reflects green light, but it appears black in red light because there is no green light reflection. Another example is a piece of white paper, which is white under white light, red under red light and green under green light. If you use red light and green light at the same time, it is yellow.

Only the luminous body has its own fixed color, which is not affected by other light and the reflected color of the surrounding environment. In this sense, a non-luminous object has no "intrinsic color", and its color is determined by its own physical structure and surrounding light conditions, so it is called conditional color.
