All of these objects only have one material zone. The capsules are set up to show you the two-layer shader I developed. The bottom layer can be a dielectric (plain diffuse) or metallic (shiny metal) surface. Above that is the simulation of a thin coat of semi-transparent (colored) material. You can change the base color, as I've demonstrated, although the most common base is diffuse white, or silvery (white) metal. However, gold is commonly used as well and I'm showing that on the third capsule.
The angle between the observer and the material, as well as the Fresnel refraction effect, must both be considered in order to get the color change to come out right. It's some neat math. However, keep in mind there is no refraction here. There are not really two layers of geometry - just one.
Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
