Notification Color not work

Mobile Apps Home Assistant Companion for Android
1

I don’t know if this is a Mobile Apps or HA problem

in agreement with:
https://companion.home-assistant.io/docs/notifications/notifications-basic/#notification-color

data:
  title: "Motion Detected in Backyard"
  message: "Someone might be in the backyard."
  data:
    color: "#2DF56D" # or "red"

The background color remains white and does not turn red.

Would it be possible to work around the problem via CSS?

Thank you

P.S. Android 13

every device is going ot handle this differently, some may color the notification and others may not. My Pixel 8 Pro will color the app icon but not the background

thats not allowed here, only basic HTML formatting is allowed but again depends on the device for how its supported
