Metameric colours?

• I could do with some advice or information please. Metamerism relates to the way colours change under different lighting conditions: http://en.wikipedia.org/wiki/Metamerism_... I'm looking for information on how to identify colours that shift more markedly than other colours as the lighting changes - I want to use this property in my photography. I've already made one image which seems very metameric - it's interesting as it means you can hide or reveal other pictures within an image as the light changes. ;) e.g. are saturated colours or pastel shades more liable to shift markedly under different lighting? Any general rules?? Any help or advice would be much appreciated, thanks!!
