Color Test/Model Cels
Like settei/character models, model cels are references that help a film/series remain consistent. While character models define how a character should look, model cels define what color(s) they should be. These cels are often simple and may feature one or several characters. Model cels are far more common in pre-2001 animation, having fallen out of use as digital coloring became common practice. As a replacement for model cels, modern character models will often include a color guide that references the digital colors.
Collector's Note: The rarity and value of a model cel will vary from series to series and character to character. See some examples of model cels below:
The main character model cel for The Completely Mental Misadventures of Ed Grimley.
Model Cel of Tsukishiro Yukito from Card Captor Sakura the Movie in a traditional Chinese outfit. This movie had a complete set of model cels made for each outfit used in the movie.
