This results in three functions, r(l), g(l) and b(l), the rgb colour matching functions of the cie system. These photoreceptors are called cones and are responsible for. The perception of color is formed in our brain by the superposition of the neural signals from three different kinds of photoreceptors which are distributed over the human eye's retina.

• if a specific color is given as (r,g,b) and k is a number smaller than 1, then (kr, kg, kb) has approximately the same hue and is dimmer. They're often packed together (sometimes with a fourth value, called alpha, or a), and the packed value is called the rgb (or rgba) value.
