Hi Wendy, I cannot verify the statement, though I suspect it is true, with qualifications. Any browser that supports CSS1 would support support the 16 color names you note from the CSS1 spec. However, I do not know that all CSS2-supporting browsers support all 140 colors in HTML Source's list, or that they would map those names consistently to the same RGB values. (Will all current browsers map Papayawhip to #FFEFD5? No comment on "indianred.") When this subject came up a year ago, Kynn suggested that we amend the recommendation to say "use the 16 named colors defined by CSS level 1, or use RGB colors" [1]. This suggestion still seems reasonable to me.
