Iridescent clouds

This was the end of the first day of a week long trek to the top of Roraima, the highest (2723 m) table mountain (Tepui) in Venezuela, and what a start!

The dry season should have started long ago, instead countless thunderstorms supplied plenty of rain showers and this particular cloud pushed a layer of thin cloud upwards and ahead of it during sunset, producing this beautiful iridescence. My first thought was that this was nacreous clouds (polar stratospheric clouds), as the various colors and hues were so similar to that of the nacreous clouds. But the nacreous clouds only occur on high and low altitudes (from around 60 degrees north and south).
