A colour value may either be a hexadecimal number (prefixed by a hash mark) or one of the following sixteen colour names. The colour values "#800080" and "Purple" both refer to the colour purple. The colour names are case-insensitive.
 | Black | #000000 |  | Silver | #C0C0C0 | ||
|---|---|---|---|---|---|---|---|
 | Gray | #808080 |  | White | #FFFFFF | ||
 | Navy | #000080 |  | Blue | #0000FF | ||
 | Teal | #008080 |  | Aqua | #00FFFF | ||
 | Green | #008000 |  | Lime | #00FF00 | ||
 | Olive | #808000 |  | Yellow | #FFFF00 | ||
 | Maroon | #800000 |  | Red | #FF0000 | ||
 | Purple | #800080 |  | Fuchsia | #FF00FF |
Popular browsers try to support all 216 (6×6×6) combinations of the 6 values 00, 33, 66, 99, CC, and FF. The following table shows colour names and corresponding values for some colours supported by the X Window System and Netscape.
OS/2 Netscape 2.02 and 4.61 insist on an e in "lightgrey" and otherwise on an a as in "gray". The name "Aliceblue" shown for "#F0F8FF" in Netscape's JavaScript Reference does not work with OS/2 Netscape 2.02 (obviously a bug, see binary). The effects in your browser are shown below. It's interesting to view this page with a monochrome (grayscale) filter - at least it convinced me that white on red might be much better than black on red.

Note that "Cyan" is an alias of "Aqua"
and "Magenta" is an alias of "Fuchsia".
Appendix G of HTML & XHTML (4th ed. 2000, O'Reilly) mentions five additional colour names "Lightgoldenrod", "Lightslateblue", "Lightgray", "Navyblue", and "Violetred". Appendix G does not list "Crimson" and "Indigo", but maybe this belongs to the errata.
OS/2 Netscape 2.02 and 4.61 show "Lightgoldenrod" and "Lightslateblue" as ordinary "Blue". "Lightgray" is shown as a lighter variant of "Darkblue", maybe "#000099". "Navyblue" is shown as something like "#A0B0E0" instead of "Navy". "Violetred" appears as something between "Aqua" and "Skyblue".
Many colours may have variants like "Blue1", "Blue2", "Blue3", and "Blue4", where "Blue1" and "Blue" are equivalent. Netscape does not support the X11-scheme, the variants of blue are actually shown as one red colour.
There may be also 100 variants of grey from "Gray1" upto "Gray100", where "Gray75" and "Gray" should be equivalent. With Netscape you'll see only some greenish colours or black instead of the lightest "Gray100" variant. The effect is different but still wrong for "Grey1" upto "Grey99", see below.
| lost names: | crimson | #DC143C | indigo | #4B0082 |

| blue | blue1 | blue2 | blue3 | blue4 |
| gray | gray25 | gray50 | gray75 | gray99 |
| grey | grey25 | grey50 | grey75 | grey99 |
Note that OS/2 Netscape insists on an e in
"lightgrey" and otherwise on an a as in
"gray".
