Change the color of an icon depending from another entitiy

[juuhee84]

Hi guys!

I am trying to realize the following:
If my car is charged in PV surplus mode, I get this information in a special entity.
Now I want to change the color of the icon for an individual device (or also for the battery or all the others) depending from the state of this additional entitiy telling the "charging mode", e.g. green when the car is charged by PV surplus, red when it is charged by power from the grid.

Is there any possibility to realize this?

Thanks,
Julian
