So, to be honest - I’ve somehow lost the focus on the main discussion about the Icon colors - therefore, I am not able to catch what I might need to acheive the configuration I want for some entities…
I have set the “default” active color to green for my binary sensors.
Right now, with running HA 2022.12.4 - some of the issues that came across with the color options have been fixed by the team, but still - there are things I would like to be different…
this image is probably a good example:
The “Doors” - lock entity on the right is red, when the door is unlocked.
That’s ok… but I would like to have the default Icon color in red…
Right now, I don’t think that this is possible by default, so I would consider to use card-mod as an alternate solution for now.
Also, there are the binary sensors:
Binary_sensor.door → device_class => lock
which is only “ON” when unlocked, and then it does show the “binary sensor color” for active, which is green.
I would like to change that, too…
OFF => green (locked)
ON => red (unlocked).
The same applies for the entities with device class DOOR and WINDOW…
How could I change that with CardMod?
I am not yet very used to card mod… the only thing I’ve done so far is changing the Header on entity cards, as you can see from the Screenshots… 
Thanks
