"An Adventure in Color/Mathmagicland" is the first episode of Disney's long-running anthology series to air in color. It premiered on September 24, 1961, as Walt Disney's Wonderful World of Color following the series' move from ABC to NBC. This show introduced a new character, Ludwig Von Drake, who provides an interesting lowdown on color (at one point performing "The Spectrum Song", all about different colors). By the end of the song, the NBC Peacock makes a brief cameo as a "color show-off". The kaleidoscopic intro to the show featured music composed by Richard M. Sherman and Robert B. Sherman. The second part of the show is the 1959 featurette Donald in Mathmagic Land.

The episode was partially created to help promote color televisions.
