GUI very inaccessible with dark GTK themes

[chewi]

I've used dark themes for years, and while they have presented some challenges, it's generally not too bad these days. sc-controller is an exception:

I've had a look at the code but SVGs and GUIs are not my strong point. As a quick local fix, I ran Inkscape over the controller and button images in bulk.

inkscape -g --batch-process --verb=org.inkscape.color.negative --export-overwrite images/{controller,button}-images/*.svg

It's not perfect but it's not bad either. I saw there are some recoloring functions in the code. Could these help?

Same problem with breeze gtk black.
