Just found this thread; I saw a b&w postcard on eBay of the Conrad Hilton's Normandie Room this week, and the chairs and round settee looked like Normandie's.
Judging from what I have read that Normandie was intended to be a Ship of State, and that the intention from the start was to have her decorated with works from anyone who was Anyone in the French world of art at that time, I find it unlikely that those interiors could have been completed in any better taste. Every artist involved pulled out all the stops on his/her individual commissions. Think in terms that Normandie was not going to be anything other than a museum piece of French art in the early 1930s. Museums are pretty cool, but who would want to live in one all the time? No, Normandie was as tasteful as it could be.
Also, as has been said before in this thread, when creating those monumental rooms, everything has to be monumental. The Grand Salon's ceiling was THIRTY FEET high. Paint a room of that proportions a nice, tasteful color, and it looks pretty dull. Also, remember that it was the beginning, the roots, of the glitz that is cruise decor today. The public rooms were intended to be stimulating, not restful. The idea was that those wealthy enough to afford first class passage would want to think of themselves as actors and actresses, spending the four-ish days in rooms that were actually stage sets for the shipboard dramas they were living.
Yep, I feel Normandie's interiors were as Glamorous as they could possibly be, and as tasteful as they needed to be. It's no mistake you have recognized the two small lounges adjacent to the Grand Salon were more restrained. Those in charge of the interiors were aware of what they were doing.
