Iridescent vs nacreous clouds:

#Nacreous clouds, also known as polar stratospheric clouds, form at high altitudes in the stratosphere and are known for their vivid colors, especially during twilight. #Iridescent clouds, or irisation, can occur in various types of clouds at lower altitudes and display pastel colors due to the diffraction of light through small water droplets or ice crystals.
