Color Values
HTML colors are defined using a hexadecimal notation (HEX) for the combination of Red, Green, and Blue color values (RGB).The lowest value that can be given to one of the light sources is 0 (in HEX: 00). The highest value is 255 (in HEX: FF).
HEX values are specified as 3 pairs of two-digit numbers, starting with a # sign.
16 Million Different Colors
The combination of Red, Green, and Blue values from 0 to 255, gives more than 16 million different colors (256 x 256 x 256).If you look at the color table below, you will see the result of varying the red light from 0 to 255, while keeping the green and blue light at zero.

Web Safe Colors?
Some years ago, when computers supported max 256 different colors, a list of 216 "Web Safe Colors" was suggested as a Web standard, reserving 40 fixed system colors.The 216 cross-browser color palette was created to ensure that all computers would display the colors correctly when running a 256 color palette.
This is not important today, since most computers can display millions of different colors. Anyway, here is the list:
