When you said "washed out" I immediately thought of those 50s and 60s photos that look soft and colorful. You know, the kind of lens effect when they want something to look 60s on TV? That would be great for FaceGen to make the 50s-70s look different.
I think Sepia works fine for Deadball era and B&W for the 1920-50s. The 4th effect needs to be for the later eras. With 80s to today being the sharpest.
