Retro / vintage color palettes?

Hey all. Hope this finds you well. Im a big big fan of Blue Note Jazz vinyl record covers. I'm in fact going to be designing a few vinyl releases myself soon, taking lots of inspiration from Blue note.

Ive spent some time googling, looking online for vintage retro color palettes but the problem generally seems to be that they are listed in RGB. I will be printing the vinyl obviously in CMYK so wondering if anyone has any good suggestions on where i might be able to perhaps even download some great vintage-retro color scheme palettes that are for printing. As a base for my design i will probably use a nice off-white cream kind of color that a lot of these Blue Note records typically have used. If anyone can recommend please let me know. Many thanks!
