Question

How is white light created by complementary colors?

Answer 1

White is created by mixing allcolours in the visible spectrum. Really, you can't "make" the colour whitebecause of this fact, except on a digital screen- The colour white is created with a mixture of red, green and bluelight on your screen

Answer 2

The complementary primary–secondary combinations are red–cyan, green–magenta, and blue–yellow. In the RGB color model, the light of twocomplementary colors, such as red and cyan, combined at full intensity, will make white light, since twocomplementary colors contain lightwith the full range of the spectrum.
