Behind The Scenes Secrets: The Wizard Of Oz
Early Technicolor

If you look closely during the song “We’re Off To See The Wizard,” you can see shadows of the spotlights and camera equipment on the grass.The Wizard of Ozwas one of the first non-animated films to use the new technicolor process. This did not mean it was always smooth sailing. For one, early technicolor needed a ridiculous amount of lighting. Of course, the lights back then were extremely hot which made the set around 100 degrees quite often.
Several tweaks had to be made to the set and costumes in order to get the color just right. For instance, Judy Garland’s white dress was actually pink as it was easier to shoot and showed up better on camera. Another similar instance is that the yellow brick road actually showed up green after the technicolor process so it had to be redone.
