Definition and Usage

The rgb() function define colors using the Red-green-blue (RGB) model.

An RGB color value is specified with: rgb(red, green, blue). Each parameter defines the intensity of that color and can be an integer between 0 and 255 or a percentage value (from 0% to 100%).

For example, the rgb(0,0,255) value is rendered as blue, because the blue parameter is set to its highest value (255) and the others are set to 0.
