Small details of today's cirrus clouds.
Images have been enhanced to better show different colors.
Most colorful areas are part of circumzenithal arc - halo effect caused by refraction of sunlight through ice crystals and some colors are probably also part of irisation caused by diffraction.

Within about 10° from the Sun, diffraction is the main cause of irisation or iridescence.
Beyond about 10°, however, interference is usually the predominant factor.
This phenomenon can extend to angles exceeding 40° from the Sun.

avec un nuage iridescent:nuage peu épais dont l'écartement des gouttes ou de cristaux de glace provoque, par diffraction, une irisation de la lumière, donnant un aspect coloré au nuage, rappelant un arc-en-ciel.

Did you ever see the nacreous clouds?
They form when unusually cold temperatures in the usually cloudless lower stratosphere form ice crystals.

Irisation in the sunset 🌇
(I just learned that this phenomenon in the sky actually has a name - "cloud iridescence"! I've seen these all the time, but I never knew it had an actual name! Hooray, science is so fascinating & neat!)

*Atmospheric Optics*
‘C’ is for cloud iridescence. This colourful optical phenomena appears on clouds close to the Sun or Moon. It’s caused by diffraction (small water droplets or ice crystals scatter the light) and is also called irisation, after the Greek goddess of rainbows, Iris.
