Basically, the three-digit version is a compressed version of the six-digit ( #ff0000 becomes #f00, #cc9966 becomes #c96, etc.). The hex number is prefixed with a hash character ( #) and can be three or six digits in length. We are generally used to the decimal number system ( base-10, from 0 to 9), but hexadecimal has 16 digits, from 0 to f. Hexadecimal (previously and more accurately known as “ sexadecimal”) is a base-16 number system. The three values in the RGB value are from 0 to 255, 0 being the lowest level (no red, for example), 255 being the highest level (full red, for example).
