and what would be a good color palette for it?
I would say its 1950s Deco-Moderne. I am not sure what you mean by color palette? Do you want to refinish or paint it?
I agree, 1950s. When choosing a color palate, I like to consider a few things.
Am I using in my own home to go with existing decor?
Do I want to stick to the original look of the piece?
If you want to keep with the look of the piece, I would good deco-modern furniture and look for similarites in the finishes on the images you fine.
