Yes, I know the preview sucks, but nonetheless I'm bringing you
KolorME - the chameleon of the KDE Themes!
It comes with a script that changes the colors for you. You can use whatever color you desire. Ain't that cool? Over 16 million themes in one!
I think it's pretty self-explanatory, but if you have further questions, feel free to ask.
Oh, btw, it needs QtCurve.
