The Golden Age of comics was from 1838 to 1950 and I recently ran across these comic book color charts from that era. If you're looking for some mid-century paint colors, these could be an interesting place to start. Or, if you wanted to do a super hero nursery in a mid-century home these could give you a perfect mid century modern color palette.
I also ran across a comic book color chart from the modern age of comics, after they switched to Pantone coloring.
If you are going to do a super hero nursery, this will give you the perfect paint colors, especially if you use Pantone paints.
