Color ValuesCSS colors are defined using a hexadecimal (hex) notation
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 (hex
00). The highest value is 255 (hex FF).Hex values are written as 3 double digit numbers, starting with a # sign.
Color Examples

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.
This is not important now, since most computers can display millions of different colors, but the choice is left to you.
The 216 cross-browser color palette was created to ensure that all computers would display the colors correctly when running a 256 color palette:
