Entity card – change color based on entity state

Hi, I have following entity card, and I would like to change the color of „Now“ entity. If the entity’s state is more than 50%, then green color, if less than 50%, then red color. So, in this case, the number „11%“ should be red.
Thank you

You might try two conditional cards, one if the state is > 50%m and one if it is < 51%. Since they can’t both be true you will only ever see one, and the colour will appear to change.

For example:

      - type: conditional
        conditions:
          - condition: state
            entity: binary_sensor.window_open
            state: 'off'
        card:
          type: tile
          entity: binary_sensor.window_open
          name: Windows
          tap_action:
            action: none
          icon_tap_action:
            action: none
      - type: conditional
        conditions:
          - condition: state
            entity: binary_sensor.window_open
            state: 'on'
        card:
          type: tile
          entity: binary_sensor.window_open
          name: Window
          color: red
          tap_action:
            action: none
          icon_tap_action:
            action: none
          card_mod:
            style: |
              ha-card { 
                {% if is_state('binary_sensor.window_open', 'on') %}
                --ha-card-background: #6c1919;
              {% endif %} 
                }

Here is the solution. Thank to LiQuid_cOOled.
