It was just luck that made me look out of the window at the right time to see this amazing sight over the Glens. We'd been driving through Glen Clova the day before and seen a rainbow cast across the grass. Something I'd never witnessed before. This must've been the same phenomena.
You can see the spectrum of colours across the Glens which my camera managed to pick up using the museum setting. The picture was taken through glass as I didn't have time to open the window.
