In the RGB system of color representation, a color is represented by the intensity of the three additive primary colors: red, green, and blue, with each value ranging from 0 to 255. Here are the encodings for some familiar colors:
The applet displayed below lets you experiment with the effects of various RGB values.
You can set the intensity of a particular primary either by moving the appropriate
slider or by typing a new value in the appropriate box. After
typing a new value, be sure to press "enter" or "return" to have it take
effect.
For best operation,
be sure your monitor is set for at least 16 bit color (Thousands of colors).
