This applet allows you to mix three colors of light (red, green, and blue) and see the resulting color. This is an example of additive color and is representative of emission, it is not the same as mixing colored paints (an absorptive, or subtractive process). To change the mixture of three colors just drag the slider to a new position. The number at the bottom represents the amount of red, green, or blue present in the mixture - 1 means 100% of the specific color, 0 means 0% of the specific color.
