Note that kdeui links with kdefx, so, if anything, kdefx underpins 
kdeui.

The reason Andreas and I suggested kdefx was that it fits in with the 
nature of kdefx - it provides a general visual effect, rather than a 
specific visual widget.  Although kdeui/kernel provides non-widget 
things, they're interaction-with-X11/OS/etc style classes, which KColor 
doesn't really fit into.

If it were to go into kdeui, I'd say kdeui/util.

I guess it depends on how generic KColor is going to be - if it's there 
purely for blending, then I'd go for kdefx.  If it's a colour 
representation class that is (potentially) useful in other contexts, 
then kdeui/util is probably more appropriate.

PS [and rather OT]: is it just me, or kdefx a bit random?  Is there a 
reason for it being a separate library, rather than a subdirectory in 
kdeui?

And KCPUInfo just doesn't seem to fit - although it's there purely for 
the benefit of KImageEffect, it's also an exported interface, and 
linking against libkdefx for KCPUInfo certainly isn't intuitive...
