Card_mod: Change the backdrop color of one selected mushroom chip at a time out of seven

Configuration Frontend

I have created a seven-day scene with a mushroom-chips-card. I would like to have the background to change only when it is selected. I’ve been attempting to do that with Card_mod. I’m new to HA and have looked around the board for something comparable, but I haven’t seen anything yet. This is my page’s screenshot:

  - type: entity
    entity: scene.eve_flarecolor_ab_mon
    card_mod:
      style: |
        ha-card {
          #--chip-background: white;
          --chip-background: 
		{{ 'green' if is_state('scene.eve_flarecolor_ab_mon', 'on') else 'red' }}
        }
