What 3 colors make up the colored shadows of the hand?

The colored shadows created when light passes through a hand typically consist of red, blue, and green. When the light is blocked by the hand, these colors mix in various ways to create different hues in the shadows. The phenomenon occurs due to the additive nature of colored light and the way our eyes perceive color. Each shadow can appear as a combination of these primary colors depending on the light source and its angles.
