Basic Color Names

The HTML 4.01 specification defines sixteen named colors, as follows (names are defined in this context to be case-insensitive):

These 16 were also specified as sRGB and included in the HTML 3.0 specification which noted "These colors were originally picked as being the standard 16 colors supported with the Windows VGA palette." It should be noted that fuchsia is exactly the same as magenta (in the X11 color names) and similarly aqua is exactly the same as cyan.

It should be mentioned that all color values from #000000 - #FFFFFF (16,777,216 colors) are valid.

Nonstandard HTML recognizes other X11 color names, including "orange," "darkgray" (which, ironically, is lighter than gray), "darkorange," "lightgray," "darkgreen," "beige," "tan," "brown" and others.
