Just discovered the Shelf plasmoid, which could be mightyly useful to me, if only I could read the labels
It's black text on dark-grey background. Turns out, it has to do with the plasma theme I use. I like the theme and don't want to switch it though.

Is there currently a fast, lamer-friendly way to specify a custom color on a widget basis (KDE 4.6)? So far, the only way I see is to edit the plama theme, but I don't want to invest that much time.
