Okay, I love pairing papers with eras! My undergrad was in fashion journalism so my go to for inspiration is the world of fashion and fabric. Here's a fun site:

70's colors: avocado, brown, mustard gold, orange; if you want to go with a brighter color palette, you can borrow from the wild, psychedelics of the 60's!
