Rare iridescent clouds appeared while hiking in intense heat and bright sun

I was hiking and suddenly saw these rainbow clouds and I thought I was becoming crazy because of the effort and the heat, also because I am colourblind. However, when I came back home, I sent the videos to my friends and they also saw the rare colours so it was not only me. I googled it and realised those were iridescent clouds.
