Dynamic icon_color for custom:mushroom-entity-card

I have the following entity card displaying some information next to a small icon. I need to make the color of the icon change based on the status of a second entity. How can this be done?

type: custom:mushroom-entity-card
entity: sensor.dogfeedtime
icon: mdi:food-fork-drink
name: Dog Fed
icon_color: blue

did you ever figure this out?

Use the Mushroom Template Card.
