About 18-bit (6-6-6) Color Mode
18-bit color uses 6 bits each for red, green, and blue components (0-63), allowing for 262,144 unique colors. This format serves as a middle ground between High Color (15-bit) and True Color (24-bit). With 64 possible values per component, it can represent subtle color gradients quite well while using less memory than 24-bit color. This format was used in some LCD panels and specialized graphics systems where a balance between color quality and resource usage was needed.
