Thanks! :-)

Yes indeed! There are a couple possibilities; in KCS there is 
shade(QColor, ShadeRole) if you want a similar color with a different 
luma (probably what you're thinking of for 'contrast colors', 
particularly since all shade roles are safe on blacks and whites). The 
more low-level goodies are in KColorUtils, particularly mix() (which is 
long overdue), overlayColors()* (if you need to use Qt's blending 
modes), tint() (for changing hue and chroma without changing luma so 
much - warning, unlike the other methods the algorithm is not fixed), 
and then shade(), darken() and lighten().

(*...but I may yet bring this up for review, since there is a potential 
that Pigment would supplant it.)

Should any of these be mentioned more prominently?

Also if you want to do something that is currently not supported, please 
tell me about it. It's really late to be making changes in 4.0 but if 
you can make a case for kdelibs inclusion you have a very good shot at 
the next release.

Hehe, I pretend to be a core developer ;-). Seriously, I was not 
offended at all, you raised a very good point that truly needed to be 
addressed, and I thank you for that.
