validator rejects "orange" but standard includes it

 The CSS Validator is claiming that a background-color of orange
 is an error.  However, at
 http://www.w3.org/TR/CSS21/syndata.html#value-def-color
 orange is definitely listed, both in the textual list and in the
 set of colour blocks.

 One's impression is that something is wrong either in the published
 standard or in the validator.  I'd have said definitely the
 validator, but in Bugzilla's list of reported errors, one is a
 report that it did not report orange as an error for a border colour.

 I haven't explored any further to see if other colours fall into
 this situation.
