Each pixel of a computer screen is a combination of three tiny, light-emitting devices that are pure red, green or blue—hence, the name "RGB." Roughly speaking, our eyes are sensitive to just these colors, and our brain conceives of all the other colors—yellow, turquoise, purple, and so on—as combinations of these three. Just for fun, how quickly can you find the color components that comprise the color on the right?
