How Many Extra Colors Did the Atari STE Display

The Atari STE offered a significant graphical upgrade over the original Atari ST, primarily through an expanded color palette available to developers. While both machines could display sixteen simultaneous colors on screen in low resolution, the STE increased the total available palette from 512 to 4096 colors. This article details the technical differences between the two systems and explains exactly how many extra colors the STE hardware supported compared to its predecessor.

The original Atari ST utilized a shifter chip capable of addressing a 9-bit color space. This configuration allowed users to choose from a total of 512 distinct colors when designing graphics or setting up display registers. Despite this limitation, the system was popular for its time, though developers often found the restricted palette challenging when attempting to create smooth gradients or detailed sprites within the sixteen-color simultaneous display limit.

In contrast, the Atari STE enhanced the video circuitry to support a 12-bit color space. This upgrade expanded the total palette to 4096 colors, providing developers with 3584 additional color options compared to the original ST. Although the number of colors displayed simultaneously on the screen remained capped at sixteen in low resolution, the larger palette allowed for much richer color selection and reduced banding in visual outputs.

Ultimately, the difference lies in the available palette rather than the simultaneous on-screen count. The Atari STE provided 3584 extra colors in its total palette compared to the original ST’s 512. This enhancement made the STE a more capable machine for graphic-intensive tasks and gaming, marking a clear evolution in the Atari 16-bit lineage.
