SUMMARY

Please add support for XDG desktop portal’s accent color setting in Qt/Kirigami/KColorScheme. Where exactly this should be implemented I don’t know, so I’ve filed this without a specific component. As a reference, the color scheme (light/dark mode) setting from the same portal is already implemented and works in at least some KDE/Qt apps. 

This would be nice to have as this is a cross desktop setting that works on most distros/desktops. Also the portal works out of the box in sandboxed apps like Flatpaks.

What might be tricky is handling conflicts between an accent color from the portal and from other ways of theming Qt/Kirigami apps.
