64-color color scheme

Quick answer：

A 64-color color scheme refers to a palette that includes 64 distinct colors. It is commonly used in early computer graphics and web design, where color palettes were limited by the hardware and display capabilities. These schemes often use a reduced color gamut to ensure compatibility across different systems. In web design, a 64-color scheme can be implemented using hexadecimal color codes that consist of six digits, with each digit representing a single color component (red, green, blue).
