I have to test this more, indeed probably won't work.
I am not sure that would be really workable out of the box, but if the color scheme \
(name?hash of the actual colors?) is inserted in the pixmap cache key, then it should \
work (having a setter/getter for a custom color scheme in kiconloader could even work \
for applications that use light and dark color schemes at the same time in different \
places, provided they have different instance of kiconloader and load directly with \
kiconloader the icons in the areas that are using a different color scheme than the \
system wide one)
