Nothing of the kind. There is no "final CSS 2.1" yet, and the concept of 
"validity" is just confusing here.

Didn't you read all of my message? (That's typical when people quote all of 
a message: comprehensive quoting indicates lack of comprehensive reading.) 
You seem to have missed this, among other things:

There are different syntax definitions for CSS, at varying level of 
formality and exactness. Hence, "valid" is an obscure word in CSS context. 
But it is pretty easy to check a simple thing like allowed color names just 
by looking at a CSS specification or draft (though the most sketchy drafts 
might be unclear even in such simple matters).

The CSS linter at http://jigsaw.w3.org/css-validator/ checks against some 
unspecified variant of CSS 2.1 by default and has a dropdown, hidden behind 
"More Options", to select the "profile", i.e. version of CSS to be used. I 
have no idea what you have done if it applied CSS 2.0 on your stylesheet, 
unless you had selected it.

The latest specification is CSS 2.0, but it makes no sense to use it, since 
no browser supports it and the W3C does not recommend it, despite its being 
the newest W3C recommendation. CSS 2.1 is the de facto excuse for a 
specification-like product but it is a draft that may, in principle at 
least, change in any way while I'm writing this sentence. Confused? You're 
not alone.
