Pick a color. Pick another.

No. The pixel-by-pixel color swap runs in your browser. Your photo never touches our servers — we don't run an image pipeline at all.

Click the Eyedropper button, then click anywhere on the photo. The pixel under your click becomes the source color. The eyedropper reads from the original photo, not the recolored preview, so you can keep sampling even after applying a swap.

When on, the recolored pixels keep their original brightness — shadows stay dark, highlights stay light, just shifted to your target color. When off, every matching pixel becomes a flat target color (cartoon-style). Preserve is the natural choice; flat is good for graphic posters.

Drag tolerance up to catch more variation in the source color (covers shadows and highlights of the same hue). Drag down to be stricter (avoids catching adjacent colors). Edge softness fades the swap at the boundary, hiding hard edges where the swap stops.

Pixel-distance matching works best on solid-color regions. Patterned fabrics with multiple colors per inch are harder — you can run the swap multiple times (once per pattern color) to recolor each separately. Or use a more advanced editor with object-aware selection.

Real green shirts contain many shades — from deep shadow green to highlight white-green. Tolerance has to be wide enough to cover the full range. Bump it up. If background plants are getting caught at high tolerance, try lower with edge softness 80%+ to feather the unwanted catches.
