Yes, I realize the diffusion factor and all (reflection <vector>), it
was the intent to see how the fading occurs for some basic pigments. I
simply used default values while testing this multiple reflection stuff.
The example remains similar concerning how rgb 0 does not fade object
reflections and rgb 1 does most, despite other finish properties.
