I am trying to tweak an Aurorae window decoration theme, but find this frustrating. I can in my SVG files inherit, for example, the properties of the Focus Decoration and Hover Decoration colors from the system color scheme. This can be done by setting the SVG object's class to "ColorScheme-ViewFocus" or "ColorScheme-ViewHover respectively, and setting the color to "currentColor". This works successfully. What I would really want to do though is to inherit the "Active Titlebar" and "Inactive Titlebar" colors from the system color scheme in the same way. However, judging by all the other Aurorae themes there seems to strangely be no way to do this. The documentation on how to inherit system colors (and how to build Aurorae themes in general) also seems rather lacking.
I assume aurorae supports all of these keys https://invent.kde.org/frameworks/plasma-framework/-/blob/master/src/plasma/private/theme_p.cpp#L386
