Controlling the tint/color of selected NSToolbarItems?

We are using lots of toolbar items with templated NSImage instances in our app.

Especially for things like the currently selected tool from a set of tools the extremely low contrast style employed by macOS 11 is a huge usability issue..

Before macOS 11 selected items were rendered in a high-contrast, inverted style.

Is there any way to control the style used to render selected toolbar items to restore usability?



Cheers,
Jay
FWIW here are some screenshots that demonstrate how much the usability has deteriorated in Big Sur.

Any ideas on how to change this back to being usable on Big Sur..?
