Unify palette across sprite sets

How it works

Upload a source sprite (the palette donor)
Upload a target sprite to recolor
Pick how many colors to keep (4–32)
Hit transfer and download the recolored result

Use cases

Match palettes across rotation frames of the same character
Unify a sprite set generated in different sessions
Snap a noisy AI-generated sprite onto a clean reference palette
Perceptual color matching (Oklab k-means) — not naive RGB

FAQ

Why do my AI-generated sprites have different palettes?

Diffusion models pick slightly different shades on every run, even with the same prompt. The drift is subtle but enough that a set of related sprites reads as 'similar characters' instead of 'one character'. Snapping every output onto a single locked palette fixes it.

What does palette size do?

It's how many distinct colors get extracted from the source. 16 is a good default for character sprites. Drop lower for chunky retro looks, raise higher if the source has shading you want preserved.

Does it preserve transparency?

Yes — transparent pixels stay transparent, only opaque pixels get snapped to the source palette.
