I think we need to make those icon colors themeable, because the dark blue and dark green ones (basically the first 10 on the config page from the screenshot), will be trouble in the dark theme mode I think.

Looks good! Ok to merge when dark mode colors added.

@matthiasdebaat can you provide some color codes for dark mode to use?

[ludeeus]

I don't think the BG colors will have an issue.
But the icon inside should be white(-ish) color (at least by default) for both light and dark

[balloob]

Ah yes, that looks indeed fine. SHIP IT. We can tweak it later.

Will create a better color pallet, including dark mode colors. I picked the current ones just randomly with a color picker.
