I'm actually a huge fan of the Salon colors - but then again I am renowned in the family as the one that likes burnt orange and avacado green!
WARNING: the following ramble is a large, speculatory THEORY!
I actually think that colors were a bit different back sixty or so years ago. This is probably partially due to the fact that dyes and inks have changed over time through chemical composition and manner of application, etc. Every time I see something old in brand new condition and in color I am taken a bit by surprise because all of my conceptions of what the colors of - say the 1910s - end up being completely different from the fact.
Each decade, in my eyes, has a different color pallet I associate with it. Normandie and other examples make me think of the popular colors of the 1930s having a yellow base for the majority. The exception being the Electric hot pink Schiaperelli made famous in 1936. Normandie is a catalogue of thirties colors - in retrospect this is a stupid statement, because Normandie was a product of the thirties, but ANYWAYS...
In the Forties I think you have a move toward the blue based colors, but things were still being manufactured with the yellow base. I've seen two kinds of greens in the 40's: A deep, vibrant emerald green that I would call "50s green" due to its widespread popularity during the next decade - and you get a kind of yellow, deeper grass green... sort of. Perhaps you know what I mean. In my eyes, the perfect 1940s Red is an exceptionally vibrant and rich color because of its blue base. Fifties colors are a bit different.
Late H&W Union Castle Liners are perfect examples of 50s color combinations. You get the flat Dove grey with the vibrant, almost electric blue and that is paired with the aforementioned 50s green and a flattish pink, provided by the carnations and the garish neoclassical landscape mural on the far wall...
I'll stop before I go further! I think perhaps now that all that stuff I wrote in the paragraphs now was a bit of stupidity, BUT, whatever. It makes for interesting discussion I suppose.
BTW: This doesn't mean I prefer garish colors over most, BUT I did just buy a shirt today that was the kind of color that one would see on a picnic blanket from the 60s. Hmmm....
