Why would a badge color change?

Configuration
1

I saw a lot of questions about how to change the color of a badge. I have the opposite problem: for some reason one of my badges is displayed with another color and I do not know why:

I will use the Cuisine badge (the weird colored one) and Parents to show the configuration (they are identical):

 - platform: mqtt
    name: "cuisine_battery"
    state_topic: "zigbee2mqtt/0x00158d00023d55e4"
    unit_of_measurement: '%'
    value_template: "{{ value_json.battery }}"
    availability_topic: "zigbee2mqtt/bridge/state"
    device_class: "battery"

  - platform: mqtt
    name: "parents_battery"
    state_topic: "zigbee2mqtt/0x00158d000249a87f"
    unit_of_measurement: '%'
    value_template: "{{ value_json.battery }}"
    availability_topic: "zigbee2mqtt/bridge/state"
    device_class: "battery"

They both have their friendly name customized (again, the same way)

sensor.cuisine_battery:
  friendly_name: "Cuisine"

sensor.parents_battery:
  friendly_name: "Parents"

They are not defined / customized elsewhere.

Is there a built-in mechanism which will set the color of a badged based on some value of its state?
