Each light bulb emits a primary color of light - red (R), green (G), and blue (B). Depending on which primary color of light is used, the paper will appear a different color. Express your understanding of color addition by determining the color that the sheet of paper will appear in the diagrams below.
The blue we use as an additive primary color contains light from one-third of the spectrum. Yellow contains the light from the remaining two-thirds of the spectrum (red+green). When blue and yellow light are added together, they produce white light. So one pair of complementary colors is blue and yellow. Another pair is green and magenta. Another is red and cyan. When complementary colors are combined subtractively, in equal amounts, they produce neutral grey colors, or black.
