Business Insider has an exhibit of color pictures of Manhattan from the 1940’s and 1960’s by amateur photographer Charles W. Cushman. The collection is maintained by Indiana University. All shot on Kodachrome.

Also I recommend the Big Picture as a regular “reading” for the pictures.
Dr. Michael R. Shaughnessy put up a gallery of scanned true color images from 1906 with geolocalisation added. This is pretty amazing to see various european locations in color.

The Denver Post Photo Blogs has an exhibit called “Captured: America in Color 1939-1943”.
Some stunning images taken between 1939 and 1943 depicting America, in Color. When I think about that period, I most of the time imaging black & white, because it was the predominant form of photography at the time. But color film, was already available, even to the general public.
That’s the kind of photography I love, depicting people, in everyday situations, to form our memories (of the past).
