The water droplets within a region of a lenticular cloud have a similar lifetime and are therefore similar-sized. This are perfect conditions for irisation, a colorful phenomenon caused by diffraction and interference on uniform objects.
In the picture and video presented below some lenticular clouds where captured by a sky surveillance camera pointed to south. In the second half of the video a quite stable cloud is formed directly in front of the sun. Irisation (colored stripes and patches) and coronas (same effect but circular shape) can be seen in the clouds.
