Image color replace

POST /api/image-color-replace

Recolor regions of an image: replace one colour (within a tolerance) with another. Useful for theme-swapping logos, recoloring icons, etc.

Replaces one colour with another, treating colours within a `tolerance` as the same. Useful for: - Re-tinting flat-colour graphics, logos, icons. - Theme-swapping a single accent colour across an image. - Quick "I want this red apple to be green" edits.

Inputs

Name	Type	Default	Description
image*	file	—	Input image (PNG / JPEG / WebP).
from*	string	—	Source colour name or #rrggbb.
to*	string	—	Replacement colour name or #rrggbb. Use `transparent` to erase the background.
fuzz	number (0…100)	0	Tolerance percentage around `from`.
format	enum (png \| jpeg \| webp)	—	Output format (defaults to input). PNG/WebP preserve transparency; JPEG flattens it.
