Mini-Graph Card Conditional Colours

Edit: Decided to change the icon colour instead which was quick and easy. Marking this as solved

Hi, hoping I’ve missed a simple error in this or approach. I have my graphs appearing well in my button cards. The bit I am hoping to achieve is to have the lines change colour when the motion sensor is active in the room. A simple teal when empty, orange when motion detected.

There are other dynamic elements to the cards, and they work just fine but I can’t for the life of me sort out how to add in this change.

              border-style: none;
              margin-top: -40px;
              }

That’s the card and my attempt to edit colour is

              line_color: |-
                {% if is_state('light.f1_livingroom_fairylights', 'on) %}
                  orange
                {% else %}
                  teal
                {% endif %}

With the light sensor acting as a placeholder while I experiment.

Thanks for any advice

So, you placed mini-graph-card inside button-card (along with other custom fields) which is inside swipe-card.
Question: why posting so much of unrelated code?
To get a simple answer “options of mini-graph-card do not support templates”.
