Define the state that a state_color turns an icon yellow. #6605
Description
The request
On my main Lovelace screen, I have a horizontal stack with three button cards. Each button is a person entity. The tap action navigates to the map screen. Everything works as expected, except that if I change "state_color" to true, nothing changes for these entities. It would be nice to have it turn yellow (like when a switch is on) when "home" or maybe the ability to define what state that a state_color activates on for entities that aren't just switches/binary.
This applies to all card types that support state_color
The alternatives
I have looked into some template sensors with template icons and things like that, and it works OK, but it would still be a nice feature to just work out of the box.
