Default Greenie goes red !!!

Here's an odd thing. Playing around with my True 30 DX (still going strong after a month and a balloon popper) I found that if I shine it at a red polythene bucket the spot on the inside of the bucket is red ! Same with orange polythene. If I shine it through a red glass the beam passes through green.

Any thoughts ? I can only think of secondary emmission (fluorescence) from the dye in the plastic.
