You're not crazy--just making ridiculous leaps--those are cheap chairs in a poor country and are probably ubiquitous--as for thepaint coloe--well I suspect there are no Sherwin Williams there--probably a limited st of available paints.
OTOH I have heard via Iraq that the orange jumpsuits are Iraqi Mukhabarat (intel) issue, the room does NOT appear to be in a regular house, the chairs and paint seem similar, Berg looks far paler and thinner than he did before he disappeared--and this had to be done in a place where so much blood and the screaming would be unremarked on--It is growing increasingly likely to me that he was held and slaughtered in a Mukhabarat safe house in or near Baghdad.
