Yes, and the CSS3 support of the CSS Validator is incomplete and highly
experimental, it is likely that css3-color will be a Recommendation be-
fore it is fully supported.

That depends on the CSS profile you use for validation, none of the
supported CSS profile supports these properties, using them makes
your style sheet invalid and the Validator thus reports errors. If
you think proprietary extensions should not cause style sheets to be
invalid, you should post a comment to this effect on the relevant
profile.
