I have 2 different icons that I want to use for a menu bar application, one dark and one light. I need to know when to pick one or the other (dependent on the wallpaper), how can I do this?

The two icons
The problem

This isn’t related to dark mode or light mode, but to the wallpaper’s color, having a darker wallpaper will result in a lighter icon and a lighter wallpaper in a darker icon.

Any help would be appreciated!
