Map overlay > basic color pallet / color whell

Hi everyone, i think this is my first post, so theres that.
I did not check if this suggestion already exists, so i apologize if i'm being redundant.

I was watching the PoE2 gameplay video of the ice monk and the white effects blend so much with the overlay that it reminded me of how much i dislike sand/snow maps in PoE1.
I usually play with 10~50% opacity and no borders on the map overlay because i like to see whats happening. When i need to see the map i focus on it for maybe a second and get a glimpse.
So, one suggestion is to add a feature to quick swap the color of the overlay: (maybe) set a default color and a secondary color on the options tab and swap around with a hotkey. I dont think the console gamers would benefit from having a hotkey just for this, but at least they could set a primary color that is hard to blend, fuchsia / cyan / etc.
