Django , Changing color of Boolean widget in list display

I have a Django Boolean Field which is shown with pretty 'on' 'off' buttons in the list display (green and red). Is it possible to have a third state like yellow or blue, indicating state is unknown.

PS : I have read about NullBooleanField, but that doesn't change my widget. All I need is, Django to display a third color based on a third value for my boolean field.

The rules for this are buried pretty deep in the Django admin app.

def _boolean_icon(field_val):
    icon_url = static('admin/img/icon-%s.gif' %
                      {True: 'yes', False: 'no', None: 'unknown'}[field_val])
    return format_html('<img src="{}" alt="{}" />', icon_url, field_val)

This is then called in admin/utils.py, so changing it to support multiple values may be tricky.

Fortunately, it does handle the NullBooleanField and there is an image for "unknown values" shown below:

icon-unknown.gif icon-unknown.gif

icon-yes.gif icon-yes.gif

icon-no.gif icon-no.gif
