KiCad toolbar colors are incorrect

[covertneko]

KiCad's project window and toolbars have incorrect background colors in both light and dark mode.

Originally reported here for Catppuccin, which is based on this theme.

GTK theme set to Colloid-Purple-Dark:

GTK theme set to Colloid-Purple-Light:

GTK theme set to Adwaita:

As mentioned in the issue linked above, as far as I can tell this with the background-color property from here is the cause.

I'm not sure what the implications of changing this would be, but I was able to fix my theme locally by commenting out the background-color property in the button rule in gtk-dark.css.

Colloid-Purple-Dark with above property commented out:

I don't know why KiCad use button's background color as window's background color and can not have alpha in color, if I change the button's color all gtk button's style will changed, I think this is more like a app issue

This is a really weird issue that pretty much only KiCad has, it picks the background color for its toolbars from the most random attributes, it appears to be a wxWigets issue or something, the discussion on the kicad issue tracker is useless finger pointing.
It doesn't affect just this theme, im on Orchis for example, have the same issue, and the only way for me to fix it was to set the button background color to my dark theme's background color, after that it finally started looking normal (no visible issues with anything else btw, like buttons didn't start looking black all of a sudden).
So the possible fix on the user side (that at least works for me) is to set your desired toolbar background color here before you install your theme.

Hi @okawo80085, I am also using Orchis with the same KiCad issue. I've looked around for the button background style, but don't seem to see it. I assumed it would be in gtk-3.0/gtk-dark.css. Can you shed some more light on which element you updated? Thanks in advance!

Hi @mp-strachan, i have a fork with a patch for that, i used on my machines, you can just cherry pick that commit if you want or clone the repo and install it like normal Orchis
