Varying levels of refraction. That's how rainbows work.

familiar with the concepts here, I just I don't understand how refractive patterns can be formed in this material with the mechanism they're describing - its easy to etch them in, but it seems like it would lack the definition needed if it's fluid swelling forming them via the etched patterns. I haven't had a chance to give the paper a proper read though.
