This dragon sculpture is called the "spectral" because of his spooky dichroic globe eyes.I think he looks very science fiction-y with silver airbrushing. This dragon of mine is produced by Windstone Editions.
It means two colors. With glass, it means that there is a color you see when you hold it up to light and look throough it, and a different color, when light is reflected from it. These globes actually reflect a whole range of colors, not just one other color, so I'm not sure if "dichroic" is really the correct term for them. They are beautiful though.
