How to use Replace a Color in Image
- 1. Upload the image to recolor. Add the file containing the color you want to swap, such as a graphic, icon or product photo with a flat colored area.
- 2. Choose the Color to replace, New color and Tolerance. Pick the original shade and its replacement with the color pickers, then set Tolerance to control how strictly a pixel must match before it gets recolored.
- 3. Download the recolored image. Save the result once the swap looks right in the preview. Pixels outside the tolerance range keep their original color untouched.
When to use Replace a Color in Image
Replace a Color in Image swaps one color for another anywhere it appears within a tolerance range, useful for restyling a graphic without redrawing it. It works on illustrations, icons and photos where a single flat color needs to change.
- Rebranding an icon set's accent color. A set of flat icons uses a brand blue that just changed to a new brand red. Replacing white with red across each icon, or blue with the new color, updates them without reopening the original design files.
- Recoloring a product mockup variant. A single product photo needs to show a different color option, like swapping a shoe's white sole for a different shade. Replacing the target color produces a quick variant image.
- Adjusting a diagram's highlight color. A chart or diagram exported from a tool uses a highlight color that clashes with a document's theme. Swapping it for a matching color keeps the diagram consistent with the rest of the page.
