Color a Dinosaur is coloring software for the NES, in which users are tasked, as the name implies, to color one of the 16 dinosaurs present in it. It also has a cult following on TASVideos, as throughout the site's history, most of the TASes were submitted on April Fool's Day, and thus spawned inside jokes on the site, especially by older members.
The wait is over, though, as warmCabin, in this TAS, demonstrates the four color theorem on all 16 dinosaurs and, for the first time, over 15 years since the first submission, gets a TAS of it published on this site.
