One thought on “Rainbow Reflections

  1. It looks like this is a effect involving polarisation. Polarisation occurs when light is reflected from many surfaces and also when it is passes through some transparent materials.

    In this case, the transparent panels of the trolley store and the side of the car are having a polarising effect. – similar to the tape dispenser and comb on this page – http://www.lhup.edu/~dsimanek/14/polaroid.htm
