Philippine residents caught stunning pictures of a rare rainbow cloud, with a unique formation that looked like the multicoloured flowing mane of a unicorn. The phenomenon is called cloud iridescence or irisation and it's formed from a combination of  humidity, heat, and water droplets around the cloud. Frozen water droplets in the clouds hit by sunlight at the right angle produce a rainbow of colors.
