I feel like I can almost guarantee the smoking room furniture was not green. Any interior designer etc would never ever mix red and green together. It's interesting we don't know the dining room for sure cause you see those old pics of the Mackay-Bennett that show they picked up a dining room chair from the wreck and put it on the boat. But where is it? I'm honestly always baffled that these interiors are still a mystery to us all when thousands of people were on that ship whether from her fitting installation to her sea trials to her actual sailing. Edwardians must've had terrible memories...I remember reading one survivors account who couldn't remember if her Steward was a man or woman.That's the kind of question that keeps one up at night. After we started talking about the tiling of the Smoking Room being blue-and-red, the green upholstery on the chairs no longer seemed to fit. Same with the Dining Saloon. Maybe Titanic had a burgandy upholstery on these chairs? Unfortunately, we'll probably never know, as there appears to be no evidence to indicate what the furniture looked like, colour-wise.
This points out one important lesson...what we conceive of as Titanic is really an amalgam of Olympic and Titanic.
