In 1990s-era marketing for The Simpsons, Bart was consistently seen wearing light blue shirts in place of the orange shirt seen in the series, a still-unexplained phenomenon that has been referenced within the show itself. This element of marketing was reflected in many of the show's tie-in games, often with inconsistent shirt colors between a single game:

The Simpsons Arcade Game features Bart in his light blue shirt for a majority of the game. However, in the opening, Bart can be seen wearing a red shirt for a brief moment when he jumps out of the school building.
• Most versions of The Simpsons: Bart vs. The Space Mutants depict Bart wearing a red shirt, a slight difference from orange. The Amiga, Atari ST, and Amstrad versions, however, depict him wearing light blue in gameplay, though the red can still be seen on the title screen, cutscenes, and box art.
• Bart wears a show-faithful orange in all versions of The Simpsons: Bart vs. the World. However, the sliding puzzle minigame in the NES version features an image of Bart with the light blue shirt, based on the famous "Don't have a cow, man!" t-shirt.
The Simpsons: Bart's Nightmare primarily uses Bart's orange shirt. However, the title card shows Bart with a green shirt, and the Bartman minigame has Bart wear a bluish grey shirt, Bartman being assigned the blue shirt while regular Bart wears red or orange becomes a common theme from this point.
The Simpsons: Bart Meets Radioactive Man is primarily a blue shirt game. However, in the intro, Bart begins with his orange shirt, which becomes a blue shirt when he dons the Bartman mask.
Virtual Bart, while typically showing alternate universe Barts, shows Bart with an orange shirt whenever he is in his original outfit. However, the box art shows Bart wearing blue.
The Simpsons: Night of the Living - Treehouse of Horror primarily features the orange shirt Bart, but he wears a blue shirt briefly in the intro.
The Simpsons: Hit & Run is entirely an orange shirt game, but Bart can be seen with a dark blue shirt on the box art.
• In The Simpsons: Tapped Out, the most recent Simpsons video game, Bart wears an orange shirt, but Bartman wears a blue shirt.

The Simpsons: Bart's House of Weirdness, The Simpsons: Virtual Springfield, The Simpsons Bowling, The Simpsons Wrestling, and all versions of The Simpsons: Road Rage and The Simpsons Game all feature Bart wearing only orange shirts (even when Bartman appears), while The Simpsons: Cartoon Studio is the only game where Bart only wears blue shirts. Cartoon Studio was the final game to primarily use blue shirt Bart, while The Simpsons: Bart's House of Weirdness was the first game to not have any blue shirt Bart whatsoever. The Simpsons: Bart vs. the Juggernauts and The Simpsons: Escape from Camp Deadly depict blue and red shirt Bart respectively on their box arts, but do not have color, being Game Boy games.

Attachment Bart Simpson and Godzilla were planned to be playable in NBA Jam, but were scrapped. There exists a video from NBA Jam's development showing reference footage of Bart and Godzilla action figures being filmed against a blue screen, as well as color palletes in the game's code labeled "B" and "G", which have yellow skin and green scales respectively.
