The invention of the photograph was amazing in itself.  The invention of colour even more so.These photographs of the American Depression in the 1930 show a completely different story in colour.As the 1930s came to a close, Kodak came out with Kodachrome film – the first commercially viable color film available to the general public. In 1937 and 1938, the colors were still not stable and accurate, but by 1939 Kodachrome was producing color images of remarkable precision.
