But it doesn't have to be #ff0000.

Yes, that's my point.

We may have different definitions of "well enough"...

If screenshotting will really do the right thing, then just doing 
reftests with an explicit reference seems like a much more robust 
approach, and not much more work.  Possibly less, since creating 
references is a lot simpler than trying to write complex "red-detection" 
algorithms and parallelizes well.
