"Yet, if that room was painted with a flat black paint, I mean every wall, the floor and the ceiling, AND you were dressed from the top of your head to your feet in black, then yes, lol...you would have a pure black shadow, because ONLY then would you have the possibility of NO radiosity, and then you could have pure black."

I thought radiosity was about how light is diffused from a surface. Thus, if you went into a room that had no light source illuminating its interior, then there'd be no radiosity and no colour and hence it'd be all black? I thought this would be the case no matter what colour the room was painted in (as the paint doesn't give off any light on its own... unless its phosphorescent).

OT but vaguely related - In Port Arthur (an old penal colony in Tasmania thats now just a pile of ruins and a tourist attraction) they used to have this room underground that had a double door (sort of like an airlock setup) and they'd put people down there as punishment - when I toured there, once they closed those two wooden doors, there was no light in that room... things looked damn black.
edit - thanks pumeco for all this info - hopefully will have some time to play with it :)
