I think this colour ringing really works well. I've now seen 3 this year. One I think I mistook White for Lime due to fading light and a not so good scope (now replaced by a Zeiss - ED optics make such a difference in poor light), but of the others Sigga Beta responded:

I'm glad to make a contribution to this study, and I think the feedback is really interesting.
In case you might stumble across any its worth checking what their colour schemes are, e.g. green = dark, Lime = light. Go to 'Operation Godwit' at
