Question 1

How do you convert RGB to HEX?

Accepted Answer

Each of the three RGB values (red, green, blue, 0-255) is converted individually to a two-digit base-16 (hexadecimal) number, then the three pairs are joined with a # in front — for example, RGB(29, 78, 216) becomes #1D4ED8.

Question 2

Why do HEX codes only use the characters 0-9 and A-F?

Accepted Answer

HEX is base-16, so each digit needs 16 possible values. The digits 0-9 cover ten of those, and the letters A-F (representing 10-15) cover the rest, letting each color channel be written in exactly two characters instead of three.
