rgb(redNum, greenNum, blueNum)

Creates a Color type: its arguments are integers ranging from 0 to 255 or an expression or attribute reference resolving to a number in this range. The value set is in hex form. For example:

$MyColor = rgb(255,0,0); sets a value of "#ff0000"

The individual channels of an RGB colour can be set or read using the '.red', '.green' and '.blue' Color-type data operators.
