Sub button change colour when certain entities are on

[davelegg83]

Goal

I've got a bubble card called Garden.

When this is clicked, it turns on evrything except my flood lights and porch light.

However is there a way if all the lights are off, except the Flood Lights or Porch Light that the ... icon will change colour so I know something is switched on outside?

Source Yaml

      - type: custom:bubble-card
        card_type: button
        entity: light.outside_lights
        sub_button:
          - entity: light.garden_floods
            icon: mdi:dots-horizontal
            tap_action:
              action: navigate
              navigation_path: "#outside"
            visibility: []
        name: Garden
    columns: 2
columns: 1

Which step did you already try?
