Mushroom entity card - change icon color depending the value

Hi!

I don’t think this will work with an entity card! For me, this code only works in a template card. Here’s a link if you want to do it with Card Mod.

type: custom:mushroom-legacy-template-card
entity: switch.all_switch
primary: Test
secondary: etc
icon: mdi:light-switch
icon_color: |2-
    {% if is_state('switch.all_switch', 'on') %}
      red
    {% else %}
      green
    {% endif %}
layout: horizontal
