1-bit graphics refer to a type of digital image that uses only two colors: black and white. This means each pixel in the image can either be on (black) or off (white), resulting in a very simple and high-contrast visual style. This format was commonly used in early computer systems and video games, where memory and processing power were limited. Due to its simplicity, 1-bit graphics can create striking and recognizable designs, often seen in retro games and pixel art. Notable examples include early titles from Atari and Nintendo, which utilized this graphic style to create iconic characters and environments.
