The rgb function constructs a color from three floating-point values that specify the amount of red, green, and blue. These values can range from 0 to 1. The alpha (opacity) value of the resulting color is set to 1. You can also use the rgb function to create color constants.
Examples:
rgb(1, 0, 0) ; red rgb(0, 1, 0) ; green rgb(0, 0, 0.5) ; dark blue rgb(1, 0.5, 0) ; orange
