Authentic Mid-Century Interior Paint Colors

I'm always trying to add to my list of authentic mid-century homes paint colors, and I just happened upon a few more swatches from the 1950s.

These DuPont mid-century colors are a lot more toned down than the O'Brien mid-century colors, so those might work better if you're looking for a mid-century modern paint scheme. But these feel a little more like authentic mid-century colors to me, but maybe that's because my mid-century ranch's walls are pretty close to the light gray on that first swatch.
