How does color photography and color film work?
Episode 112: Messed Up, Man (01:08)

Reveal the answer
The answer
The three-color method was suggested by James Clerk Maxwell in 1855 and Thomas Sutton produced the first color photograph in 1861. Kodachrome (1935) was the first modern three-layer color film. Digital sensors have pixels responsive to red, green or blue.
