Prompt

Apply an Indexed Color Palette effect, limiting the entire photograph to sixteen adaptive colors drawn from the source. Create visibly stepped gradients, crisp color transitions, and fine ordered dithering where intermediate tones are needed, suggesting early computer graphics without oversized pixels. Keep the original subject and composition.

Paste it into LetzAI with your own image to apply the effect ↗

Identify

A low number of colors is reminiscent of early computer graphics.

Principle

An adaptive palette1 indexes the image in 16 colors.

Try it out

Compare the hard and dithered2 versions.

Classification

Calculated image processing result.

07 AI illustration: The image compares two versions of a sunset sceneThe image compares two versions of a sunset scene. The left displays hard color transitions, while the right uses stippled dithering to simulate gradients with the same limited index of colors.Illustration generated for the Atlas (AI)
