Sure, but it is normalized, in the three UAs I tested. Another example  
that tests this scenario:

<!DOCTYPE html><body>x
  document.body.style.color = "#000"

So if you think this is ok, changing specified values should be ok too  
(and in fact already happens). Figuring out to what degree we want to  
canonicalize them was the idea of this thread. Preserving system colors  
makes sense to me, for instance.
