Flowers and Trees (1932)
Film is a technological medium, and animation is often at the forefront of that technology. So it's no surprise that when Technicolor was in its infancy, the color-film corporation found a champion in Walt Disney. This Silly Symphony short marked the first use of the three-strip process, which offered richer and deeper colors across the spectrum. Flowers and Trees won an Academy Award and inaugurated the color-film revolution; three years later, Becky Sharp was the first live-action film shot using the three-strip process.
