More with prisms 2024 

Here are a few more renders of glass. The glass material shows a colour spectrum attempting to mimic a prism. Unfortunately there is a quirk.

For each of the rainbow colours that we normally associate with a prism colour dispersion (red, orange, yellow, green, cyane, blue, and violet), I had to use a separate IOR (Index of Refraction). The problem is that a natural colour spectrum is continuous, rather than made of a set of seven colours, so it looks a bit different to what would normally be expected. The resulting effect is a bit hyperreal, but still fun.
