It looks just like an oil spillage – the same iridescence. And I guess that some people seeing this would think it is oil. But, thanks to you, I know it is something rather special. A stunning image, Linda

Thanks, Andy. It is the same iridescence—a manifestation of color interference. I’m not sure I’ve shared this web page before; it has an interesting discussion of color interference: https://www.olympus-lifescience.com/en/microscope-resource/primer/lightandcolor/interference/. This page does, too, though without illustrations: Color – Diffraction And Interference.
