[Cinnamon] Choose theme color automatically based on wallpaper

[TheCheddarCheese]

Windows had a toggle in the settings that automatically chose the accent color of the system based on the colors of the wallpaper. I'm not sure how feasible it is to implement here but it'd be nice to have something like that.

It is not very feasible. In freedesktop themes have a version for each toolkit and the colour is all over them. Often it is also found in images for things like checkboxes.

I don't know if it might be something with Gtk, Libadwaita or a mixture or both (and other stuffs), but something like the former Gradience could do with your requirement, though it only applies to Adwaita, Adw-Gtk3 theme (not sure about the real name) and GNOME Shell, to adapt it to several other themes out there you need to create a standard platform (which I guess is the not-being-feasible that @Secret-chest mentions) and that any theme can be adapted to it with fewer changes
