Colors that work great in the Dark Theme don't work well in the Light Theme.
For example, I loved having the Folder set to Green, which created wonderfully emphasized Green Links and Highlights in Dark mode, but the Green Font is too faint for Light Mode and Printouts, and actually becomes de-emphasized.
Meanwhile, Blues and Purples are great for the Light Theme, but too dark for the Dark Theme.
It would be great to simultaneously Set Green for Dark Theme Users and Blue for Light Theme Users, so All Users and Print-related needs are satisfied.
