Hexadecimal numbers

One of the ways to represent colors in CSS styles is using the base 16 number system, hexadecimal, or "hex". The hex number system uses the digits 0 through 9 (ten digits) along with the letters A through F (six digits) for a total of sixteen digits. This is how you count in hexadecimal:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 1A, 1B, 1C, 1D, 1E, 1F, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 2A, 2B, 2C, 2D, 2E, 2F, etc.
