•  Support It's really pretty, but how does a compound with only two elements produce so many colors? I guess these colors were shined through the film. -- Ikan Kekek (talk) 06:27, 30 July 2022 (UTC)

  The colours arise because of the birefringence exhibited by the crystalline film. When a sample possessing birefringence in its crystalline structure is viewed in between two crossed-polarisers, you will see beautiful colours. The colours depend on several factors including the thickness at each point and the orientation of the crystal axis with respect to the optic axis of the microscope. When a wave plate is inserted in the optical path of the microscope, it introduces a phase shift in the light beams, ultimately producing colour. Different waveplate thicknesses can give different colour palettes. Colour is not artificially applied, it's derived by the physics and chemistry of the sample and setup.

• Thanks for the explanation. -- Ikan Kekek (talk) 19:06, 30 July 2022 (UTC)

•  Support At first glance I thought this was a silk shawl or a similar fabric. Fascinating to learn this is something totally different, but as Ikan pointed out, really pretty. --Kritzolina (talk) 08:04, 30 July 2022 (UTC)

•  Weak support I second Kritzolina's take, but there are areas I wish were a little sharper, and some purple fringing that I think could be more effectively suppressed. Daniel Case (talk) 17:46, 31 July 2022 (UTC)
