Suggestion: Changes to system-icons.css (solving known color bug)

[ochi12]

machine: Ubuntu
I used an online calculator for svg filter #808080 as the base color, #808080 (note this is from ubuntu's Yaru icon)

I'm not sure if other icon themes uses #808080 as base color for their symbolic icons.

The suspect in this snippet is the extra 'filter:' word
--gnome-icons-hack-filter: filter: is supposed to be --gnome-icons-hack-filter:

/* Icons light/dark fix coloring hack filters */
:root {
	--gnome-icons-hack-filter: filter: brightness(0) saturate(100%) invert(37%) sepia(8%) saturate(683%) hue-rotate(183deg) brightness(95%) contrast(84%);
	--gnome-window-icons-hack-filter: filter: brightness(0) saturate(100%) invert(37%) sepia(8%) saturate(683%) hue-rotate(183deg) brightness(95%) contrast(84%);
}
@media (prefers-color-scheme: dark) {
	:root {
		--gnome-icons-hack-filter: brightness(0) saturate(100%) invert(94%) sepia(11%) saturate(362%) hue-rotate(184deg) brightness(95%) contrast(87%);
		--gnome-window-icons-hack-filter: brightness(0) saturate(100%) invert(94%) sepia(11%) saturate(362%) hue-rotate(184deg) brightness(95%) contrast(87%);
	}
}

Updated Snipper

/* Icons light/dark fix coloring hack filters */
:root {
	--gnome-icons-hack-filter: brightness(0) saturate(100%) invert(0%) sepia(5%) saturate(7500%) hue-rotate(295deg) brightness(104%) contrast(104%);
	--gnome-window-icons-hack-filter: filter: brightness(0) saturate(100%) invert(37%) sepia(8%) saturate(683%) hue-rotate(183deg) brightness(95%) contrast(84%);
}
@media (prefers-color-scheme: dark) {
	:root {
		--gnome-icons-hack-filter:  brightness(0) saturate(100%) invert(100%) sepia(100%) saturate(0%) hue-rotate(164deg) brightness(101%) contrast(101%);
		--gnome-window-icons-hack-filter: brightness(0) saturate(100%) invert(94%) sepia(11%) saturate(362%) hue-rotate(184deg) brightness(95%) contrast(87%);
	}
}

checking in light theme (ICONS are now black) instead of gray

Thanks, I have corrected the typo in the code. But sadly that doesn't have anything to do with the known color bug. The problem is that a different filter might be needed depending on the icon theme, so this will only work for Yaru.

so this will only work for Yaru.

Well then additional options in the about:config with help, like choosing Icon theme. Specifying the icon theme with off course string value instead of boolean or will also set the filter somewhere.
