SpongeBob SquarePants

SpongeBob is the titular character from the TV show SpongeBob SquarePants. It was created by marine science educator and animator Stephen Hillenburg and started airing in 1999. The series follows the adventures of SpongeBob and his friends in the underwater city of Bikini Bottom.

SpongeBob is a yellow kitchen sponge with blue eyes that wears brown shorts, a white shirt, and a red tie. The bright yellow color dominates his palette. In the RGB color model that television uses, yellow is the complementary color of blue, which is the main background color of the show. Because, obviously, most of the action takes place underwater.

Yellow is also a universally happy color thought to be cheerful, confident, exciting, optimistic, and friendly — just like SpongeBob.
