Iri­des­cence is the phe­nom­e­non of certain surfaces that appear to grad­u­al­ly change colour as the angle of view or the angle of il­lu­mi­na­tion changes. Examples of iri­des­cence include soap bubbles, but­ter­fly wings and sea shells, as well as certain min­er­al­s. It is often created by struc­tural col­oration (mi­crostruc­tures that in­ter­fere with light).
