OldTrapCollector 377 Posted June 15, 2010 Report Share Posted June 15, 2010 The colours in the cloud are called irisation - a kind of spectrum effect from splitting light (a bit like a rainbow I suppose) It often happens with that type of high cloud if the sun angles are right OTC Quote Link to post Share on other sites
