Problem with RGB value syntax

There is a problem with the proposed syntax for RGB and RRGGBB values.
Because both id-selector and RGB values are prefixed with '#', it is
not possible to use Lex in a straightforward way to implement the
lexical analyzer.

Reason: '#f00' would be '#' followed by a legal identifier, but '#0f0'
would be '#' and a number ('0') followed by an identifier ('f0').

Because of this conflict it would be necessary to make the lexical
analyzer context-sensitive, i.e. '#' in the selector part of a rule
and '#' in the declaration list would be handled different.

IMHO, it would be better to use a different prefix for RGB values
(e.g. '&').
