Popocatepetl Volcano – Gained massive popularity for spewing clouds of pink smoke.
The video does not explain what chemical process might turn smoke or steam this particular shade (although with the proper dyes, it is possible to turn smoke into a veritable rainbow), but it isn’t particularly relevant anyway; this video does not depict an actual volcanic eruption.
I’m a graphic artist so I find this a very good rendering of a volcano with pink smoke. I hope you enjoyed it as well as I did.
