The most commonly used color profile in the world of computers, TV screens and mobile devices is RGB. RGB is the process by which colors are rendered onscreen by using combinations of red, green and blue. Web colors can be selected by color name, by RGB values (red from 0-255, green from 0-255 and blue from 0-255) or by Hex code, a hexedecimal system of 6 digits (each digit can be 0,1,2,3,4,5,6,7,8,9,a,b,c,d,e or f). The values for Red comes from digits 1 & 2, for Green from digits 3 & 4, and for Blue from digits 5 & 6.
