Bill Melendez's 1966 television animated special It's The Great Pumpkin, Charlie Brown may not seem the obvious choice for a study in color theory. The Peanuts shorts from that era are usually considered beloved yet simple children's fare. In animation circles these specials are often footnoted as being produced quickly and on the cheap. While it is certainly true that The Great Pumpkin is not high art, it has endeared itself into the collective holiday psyche of Americans since the late 1960s. Such an emotional attachment stems from the familiarity of the characters, the breezy quality of the music, the innocence of the voice acting, and also - I believe - the use and direction of color.
Since the vast majority of artists credited to this holiday special are listed under the generic title of "graphic blandishment", it is difficult to surmise who directed the color choices in this short. My best guess is that it was Dean Spille. This study does not presume to know why all of the color choices were originally made, but instead gleans what it can by analyzing the image and noting impressions and observations. In short: I am simply studying the result, not the intent.
It should also be noted that I am not working from an original print of the film but from a digital copy made for DVD, therefore the colors that I study today may not be (and most likely are not) completely accurate to the original. While the remastered video has revealed textures and details that were lost on broadcast television, I suspect that the color saturation has been increased to suit modern tastes.
It's The Great Pumpkin, Charlie Brown begins with a sequence of Linus and Lucy selecting a pumpkin. As they walk from their house to the patch and back again, the mood of the film is subtly introduced. Near their front steps, the sky is a dusty, rose pink with very low saturation. The ground is primarily a yellow-green, with intense spots of red and orange autumnal foliage. Buildings and light poles contain pink and purples mixed down with a bluish grey, all reinforcing that the time of day is dusk.
