How do I change the mdi color icon to white?

This does not work:

type: conditional
conditions:
  - condition: state
    entity: alarm_control_panel
    state: disarmed
card:
  show_name: true
  show_icon: true
  type: button
  tap_action:
    action: toggle
  entity: input_button.arm_home
  icon: mdi:home-outline
  card_mod:
    style: |
      ha-card {background: orange};
      paper-item-icon-color: white;
grid_options:
  columns: 6
  rows: 5
