I would like to be able to se the background color of the card using some template code. I just want to set the background color to orange when the thermostat is heating.

Thanks

I managed to set the background color of the card like this:

style: |
  ha-card {
    {% if is_state_attr(config.entity,'hvac_action', 'heating') -%} 
      --card-background-color: var(--state-climate-heat-color); 
    {%- endif %}
  }
