CSS color names came from X a long time ago, but their mapping to rgb is
now part of the CSS specification.  And, apparently there were multiple
versions of this file coming from X.  The Emacs one would be ok provided
the lists are identical and will always remain so.  Otherwise, css-mode
needs its own list.

Using "css-" in the name seems sufficient to me.  Maybe a comment
explaining this would help as well.
