The hexadecimal code of the measured colour The most common way to analytically represent colour is via a 6-digit alpha-numeric HEX number, RGBA, and HSL Hex is a 6-digit, 24 bit, hexidecimal number that represents Red, Green, and Blue. There are 16 million possible colours. RGBA is similar to Hex in that it has 24 bits for RGB colour, bit there is an additional 8 bit value for transparency. HSL stands for Hue, Saturation, and Lightness. The values are based on a position from the centre of a colour wheel. The value for Hue is from 0 to 360, representing the degrees on a colour wheel. Saturation is the distance from the centre of the colour wheel. The L stands for Lightness, which represents the luminance.
