The Hexadecimal Numbering System

The hexadecimal numbering system uses 16 as a base. This is why hexadecimal numbers are also referred to as base-16 numbers. Instead of creating new characters to stand for the new numbers, we use the first 6 characters of the English alphabet. Therefore, the hexadecimal numbering system is based on the following 16 characters:

0 1 2 3 4 5 6 7 8 9
A B C D E F

Zero, "0", is the smallest representation of a color and F is 15 times the intensity of the color of 0. Combinations of these digits, using different intensities, create different shades of a particular color. Where FF is equal to a pure color hue, double zero, "00," is equal to zero or no hue.

Next, we discuss representing and mixing the colors using Hexadecimal code.
