Re: [csswg-drafts] [css-color] What happens in colo() if you pass numbers to a named colorspace, or vice versa?

it goes to the next fallback (rather than be discarded, for example).

kk, that works for me.

I just opened a separate issue for this.

non-css-4-color UAs, like:

Can't detect these errors at parse-time anyway, so you have to provide
 your final fallback twice: once in a separate declaration for legacy 
UAs, and once at the end of `color()` for modern UAs.

Cool, can you give me a decent example name?  I haven't written any 
named-color examples in the spec yet, but I need to.
