First, we turned on all the three lights and block the path with our hand. We turned off one switch at a time and observed the color of light produced when we turned off the red light or green light or blue light.
When we blocked the path of light over the table top, it produced three colored shadows: cyan, magenta, and yellow. The color of each shadow is the complement of the color of the light source- red, green and blue. These three primary colors make up white.
When we moved our hand closer to the table top, all parts of the colored shadows overlap. These overlapping areas are primary colors. The part where all the primary and complementary colors overlap is black.
