Explore recolors in 3 steps

1

Upload your illustration

Drop or click to upload a character illustration. Skin tones and outlines are detected and kept automatically. Everything stays in your browser.

2

Tap a candidate

Ten recolor variations of your artwork appear as a catalog — pastel, vivid, inverted and more. Tap one to see it large, and shuffle for ten new ideas.

3

Adjust and save

Toggle which colors are kept at any time — the chosen scheme stays put. Save the recolored image or a before/after sheet as a PNG.

How this tool works

This tool is for illustrators who want to see their character in different color schemes without any color-theory knowledge. Upload an illustration and it generates a catalog of ten recolor variations of your actual artwork — skin tones and outlines are auto-detected and kept unchanged by default. Recoloring is applied as a per-cluster hue/saturation/value transformation rather than flat fills, so gradients and shadows are preserved. Because every candidate is generated from a random seed, toggling which colors are kept never scrambles the scheme you picked. All processing is completed locally in the browser, and uploaded images are never sent to a server.

  • Deterministic extraction: Colors are clustered with k-means++ in CIELAB space using a fixed random seed, so the same image always yields the same palette and the same initial catalog.
  • Shading-preserving recolor: Each color cluster is recolored by a hue/saturation/value delta transformation instead of a flat fill, keeping gradients, shadows, and highlights intact.
  • Skin and outline detection: Skin-like colors and dark outline colors are detected heuristically and kept unchanged by default. You can toggle any of them at any time.

Character Color Analyzer

Analyze the color balance of character illustrations locally in your browser. Upload an image to visualize palette balance and study your own work or reference pieces.
