:: Developer Documentation Request Request Type: Correction Gecko Version: unspecified Technical Contact: :: Details The list of CSS color keywords does not contain "cyan", but "cyan" does appear in the list of "Extended color keywords" in the CSS Color Module Level 3 spec linked here (https://drafts.csswg.org/css-color-3/). "cyan" appears to be a synonym for "aqua" (#00ffff).
Just added it. Thanks
Thanks for the quick fix. Since "aqua" and "cyan" are synonyms, I think "aqua / cyan" should be added to the list "Several keywords denote the same colors" above the table.
