Well Bobb..... that deepends on how muuch you've had to drunk/drink!!!!
The green ones again are "green manufactured crystal". The inside of those prisms are painted with Gold Paint, which I would imagine would be related to reflection. Now the Red Prisms, a separate unit, I would basically say would be the same, as well as being the exact same size as the green ones. According to the entries on the Forum, the Red ones were never used (even though they are a lot cheaper.)
