If I choose any light Creator theme, I end up with black text on a dark background in some cases when I run Creator in a Plasma session. It's hard to tell which colors come from the application color scheme and which ones Creator is overriding. Note how the debug variables view is particularly hard to read.

On one hand, system settings make themes redundant in general, so maybe Creator should have a themeless mode (be able to set it to "none", use default QPalette colors, and use the system style for painting any custom widgets).

On the other hand, if it's going to have themes, it needs to be thorough about applying the colors to everything.

Included screenshots of both Creator (with the Flat Light theme ATM, even though I'd rather have a dark one) and the Plasma settings.
