Sonic 1 Colors Edition is a ROM hack of the original Sonic the Hedgehog for the Sega Genesis. It retains the core gameplay of the original, but features modified graphics with a vibrant color scheme and some level design changes. While the original Sonic the Hedgehog was developed and published by Sega in 1991, this is a fan-made modification, meaning its origins and production details are within the community of ROM hackers.
