nothing that i have seen; it's more that the khtml implementation is very 
simple and straightforward. i don't see how it could be much leaner. so 
that's more of a "good going" to what's in khtml than anything about kcolor. 
if the implementation in khtml was agregious in some way (which would 
surprise me, the khtml hackers are pretty damn good) then that would help 
tilt things in favour of putting in something that could replace it.

they'll have to speak for themselves, but were i to take a gander: i don't 
think it has fallen off their maps, more likely they are just busy with what 
they feel they can get done for 4.0 given how close that is and will revisit 
the colour issues later. the "HIG issue of the week" is probably consuming 
their time atm.

this was a joke about the w3c. ergo the winking, sticking her tongue out 
smiley. (yes, it's a girl. i only make girl smileys. they may me happier.)
