The Wizard of Oz (1939 film)

In his book The Wonderful Wizard of Oz, Baum describes Kansas as being ''in shades of gray''. Further, Dorothy lived inside a farmhouse which had its paint blistered and washed away by the weather, giving it an air of grayness. The house and property were situated in the middle of a sweeping prairie where the grass was burnt gray by harsh sun. Aunt Em and Uncle Henry were ''gray with age''. Effectively, the use of monochrome sepia tones for the Kansas sequences was a stylistic choice that evoked the dull and gray countryside. Much attention was given to the use of color in the production, with the MGM production crew favoring some hues over others. Consequently, it took the studio's art department almost a week to settle on the final shade of yellow used for the yellow brick road.
