Here are 220 HTML colours (of more than 16 million possibilities!).
The 6-digit hex codes used inside web pages are shown as well as the 3-number RGB values.


# For hex codes, each pair of digits sets the RED, GREEN & BLUE brightness, increasing from 0-9 then A-F (i.e. a base of 16).
# The decimal RGB values increase from 0 to 255 for each of the three primary colours.
