RGB Color Value

An RGB color value sets the red, green and blue components of the color separately. For example:

#f00 Three digit hexadecimal.
#ff0000 Six digit hexadecimal.
rgb( 255, 0, 0 ) Function notation using decimal values.
rgb( 100%, 0, 0 ) Function notation using a percentage to set a color component.

Note: These are different ways to define the color red.

Hexadecimal notation is the '#' character followed by three or six hexadecimal characters. The two notations are called three-digit and six-digit respectively. For example:

The three-digit notation is expanded to the six-digit notation by copying digits. For example, #08f expands to #0088ff. This ensures that white (#fff) can be represented in three-digit notation accurately.

Function notation uses the function name "rgb" and three parameters to set the red, green and blue components of the color.

HSL Color Value

A HSL Color Value is defined using three parameters:

Hue An angle on the color circle, measured in degrees. 0 corresponds to red, 120 corresponds to green and 240 corresponds to blue.
Saturation The percentage saturation of the color. 100% is fully saturated. 0% is a shade of gray.
Lightness The lightness of the color. 100% is white. 0% is black.
