Mobile Notification Script with colour field - Please help

1

Hi Automation Ninjas!
Thanks in advance.
I’m trying to create a script for sending a mobile notification, assigning variable as fields.
I created an RGB color field for the Icon color. Then I realised the Icon color needs to be a hex value.

Is it even possible to use an RGB color field as an Icon colour in a mobile notification script?

Any help would be highly appreciated.

alias: Mobile Notification Script
sequence:
  - service: notify.mobile_app_sobanath_s_mobile
    data:
      message: "{{message}}"
      title: "{{title}}"
      data:
        channel: "{{channel}}"
        color: "{{colour}}"
        priority: high
        importance: high
mode: parallel
fields:
  message:
    selector:
      text: null
    name: message
    required: true
    description: >-
      Send clear_notification to clear with correct tag. Send remove_channel
      with the correct channal in the channal field
  title:
    selector:
      text: null
    name: title
  colour:
    selector:
      color_rgb: {}
    name: colour
