I'm not sure fresnel is the right term. What GP referred to is probably iridescence [0].

Yeah, he didn't call the color effect fresnel. He called the reflections fresnel. You're right that the color effect is called iridescence.

If you want to know lots about how materials interact with light to look the way they do, including how the Fresnel effect contributes, there was a great talk at the Blender conference this morning about it.
