Experiment with Color



White light—the light we usually see—is made up of ALL the colors of light. That’s why, when it is broken by a prism, we get a “rainbow”. Light is composed of three primary colors, just like paint, but they are not red, yellow and blue. They are red, GREEN and blue. Since what we see on computer screens (as well as television screens) is seen by the light from the screens going directly into our eyes, the color it uses is known as RGB color—red, green, blue. All of the colors we see on these screens are made from a combination of these three colors. The actual color depends on the amount of each primary color we use. So, how do we tell the computer what to mix together?
