Many of the WPT tests matching css/css-color/predefined-*.html are failing in WebKit. The complete set that fail are:
Interested to learn what kind of failures these are. User-visible failures of some kind? Subtle failures where the tests *require* rounding color values to lower precision? Watching this space.
Fixing a few in 220940.
We could have titled this bug "14 tests failing" rather than "many tests failing".
And after bug 220940, down to 11.
Could use that style people sometimes use in bugs inside Apple: "11 tests failing (was 14)".
And after bug 221018, down to 9.
And after bug 221114, down to 7.

Actually, it is down to 8.
(When Darin wrote "down to 11", it was actually 12, and I have been miscounting since then :) ).
And after bug 221116, down to 6.
After bug 221190, down to 5.
After bug 222235, down to 2.
The final 2 will likely be removed from the test suite as fallback seems likely to be removed from the spec - https://github.com/w3c/csswg-drafts/issues/5931.
Either way, holding off on implementing fallback until that is resolved.
