W3C
Standard Color Names
W3C has listed 16 color names that
will validate with a CSS validator.
The color names are: aqua, black,
blue, fuchsia, gray, green, lime, maroon, navy, olive, purple, red, silver,
teal, white, and yellow.
Cross-browser
Color Names
A collection of nearly 150 color
names are supported by all major browsers.
Cross-browser
Color Values
Some years ago, when most computers
only supported 256 different colors, a list of 216 Web Safe Colors was
suggested as a Web standard. The reason for this was that the Microsoft and Mac
operating system used 40 different “reserved” fixed system colors (about 20
each).
We are not sure how important this is
now, since most computers today have the ability to 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:
