Websites use HTML to code their colors using 2 digit hexadecimal pairs. Hexadecimal is base 16 instead of the usual base 10. Each digit requires the numbers 0-9, plus the letters A (10), B (11), C (12), D (13), E (14) and F(15). Using 2 hexadecimal digits, you can code 16 x 16 = 256 possible colors. ................
