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.
