Change style of an input_boolean in in Entities Card with attribute type: button

Hi,

How can I change the style (icon-color and background-color) so I get a blue background and white iconwhen the input_boolean is turned on (see bottom card), instead of the default yellow icon and the same grey background:
Untitled-2

type: vertical-stack
cards:
  - type: entities
    title: Messages
    entities:
      - type: buttons
        entities:
          - entity: input_boolean.music_message_time_to_eat
            name: Time To Eat
            icon: mdi:silverware-fork-knife
          - entity: input_boolean.music_message_wake_up
            name: Wake Up
            icon: mdi:theme-light-dark

Thanks in advance,
Jelle
