The History of Limited Color Palettes in Gaming

Why were palettes so limited? Early game hardware was designed around the limitations of memory cost, processing power, and the NTSC/PAL broadcast standards. Storing color information for every pixel was expensive — so hardware designers created fixed palettes of pre-defined colors that game code could reference by index. This dramatically reduced memory requirements.

The NES palette is one of gaming's most recognizable constraints. The PPU (Picture Processing Unit) could only display 25 colors on screen at once from a master palette of 54 hardware colors (with many browns and grays). Artists learned to create stunning detailed graphics within these limits, and the NES aesthetic is celebrated and imitated to this day.

CGA graphics on IBM PC compatibles are infamous for their harsh magenta/cyan palette — a result of cost-cutting in the hardware design. The CGA card forced programmers to choose between a few fixed color combinations. Despite this, CGA-era games built entire artistic traditions around the limitation.

The SNES unlocked creativity with 32,768 possible colors (15-bit color) and up to 256 on screen simultaneously. Artists no longer had to work around a fixed palette — they could choose any colors they wanted. This enabled the painterly, expressive art styles of SNES JRPGs and the pre-rendered sprite revolution.

Palette cycling was a clever technique where artists could animate colors by rotating index values in the palette table — creating the illusion of moving water, fire, or lava without changing any pixel data. This made animations "free" in terms of processing cost.
