Color packing is a technique used in digital imaging and graphics to efficiently store color information. It involves combining multiple color channels, such as red, green, and blue (RGB), into a single data format. This helps reduce the amount of memory needed for images while maintaining visual quality. In color packing, each pixel's color is represented by a specific number of bits. For example, an 8-bit color depth allows for 256 different colors. By using color packing, software and hardware can process images faster and more efficiently, making it essential for applications in computer graphics, video games, and digital photography.
