Feature request: Icon color

[TimBeekman]

It would be amazing to be able to set the icon color like in Mushroom cards, based on en Jinja2 template, like

{% if is_state('light.kitchen','on') %}
blue
{% else %}
none
{% endif %}

You can do that with a custom style like this:

              .bubble-icon-container { background-color: ${state === 'on' ?  'blue' : 'var(--card-background-color) !important'}; }
