What determines the color of a body illuminated with white light?

The color of the body that is illuminated by white light is influenced by the light of what color this body absorbs, scatters or transmits. Take, for example, a white canvas that is illuminated by the sun. It is white because it reflects all colors. And when we apply red on this canvas, we will get red as a result, since it scatters and reflects the red color, and absorbs all other colors. When yellow and blue are applied to red, a black stripe is obtained. Due to the fact that now all colors are absorbed.
