The Nintendo Game Boy Color was released in Japan on October 21st, 1998.
During the 1990s, despite competition from Sega’s Game Gear and Atari's Lynx, the Nintendo Game Boy dominated even if it didn't have color graphics, but on this day in history in 1998, Nintendo changed that by releasing the Game Boy color in Japan.
The system had full color as opposed to the monochrome graphics of the original.
The system itself also came in colors like yellow and red.
It could show original games in color or play exclusive games that had original content.
The system had games in popular franchises like Pokémon and Mario and cult classics like Shantae.
Eventually, it would be succeeded by the more advanced system called, appropriately enough, the Game Boy Advance, and discontinued in 2004.
