When Penn and his team are zapped into a color-filled world where the colorful Hues and the gray Drabs are in a feud, they must stop Rippen from destroying the rainbow rocks.
This episode's title is a spoof of the Christmas classic It's a Wonderful Life.
Also the title is a reference to the 1946 film It's a Wonderful Life.
Color World has many references to the books by Dr. Seuss.
The conflict between the Hues and the Drabs is very similar to the Sneetches (divided into two types, as one group is comprised of those who have stars on their bellies, and the other group is comprised of those who don't) of the Dr. Seuss story of the same name from the book The Sneetches and Other Stories, and one of the three segments of the DePatie-Freeling Cartoon Dr. Seuss on the Loose.
It is revealed that Phyllis is very allergic to flowers.
