Image Color Replacer
Replace one colour in an image with another — recolour a logo, change a background, or swap a single shade.
Changing a colour without redrawing
Sometimes an image is perfect except for one colour: a logo that needs to match a new palette, a product shot you want in a different shade, a background colour that clashes. Rather than rebuild it, you pick the colour to replace and the colour to put in its place, and every matching pixel is swapped.
It works cleanest on flat, solid colours — logos, icons, simple graphics — where the colour you are targeting is well defined.
Why photos are trickier
On a photograph, a colour is rarely a single value; a red jumper is really hundreds of slightly different reds with shadows and highlights. That is what the tolerance control is for: widen it to catch all those near-matches, narrow it to swap only an exact shade. Expect flat graphics to swap crisply and photos to need a little more fiddling.
How to replace a colour in an image
- Add your image.
- Pick the colour to change and the colour to replace it with.
- Adjust the tolerance, then download.
Recolouring without redrawing
Swapping one colour for another is the quickest way to recolour a logo for a dark background, produce brand variants of a graphic, or test a palette without opening a design program. It works best on flat graphics where colours are solid and clearly separated.
Tolerance controls how similar a pixel must be to get replaced. Too tight and you leave speckles of the old colour at the edges; too loose and neighbouring shades get swept up too.
Questions & answers
Why are there leftover pixels of the old colour?
Anti-aliased edges are blended shades. Raising the tolerance slightly usually catches them.
Does it work on photographs?
Best on flat graphics and logos. Photographs contain too many shades of a colour to swap cleanly.
Can I replace more than one colour?
Run the tool again for each colour you want to change.
What kind of image works best?
Flat graphics — logos, icons, simple illustrations — where each colour is a clean, solid value that swaps neatly.
Why doesn't it catch every shade in a photo?
A photographed colour is really many close shades. Widen the tolerance to include the near-matches, or narrow it for an exact swap.
Is the image uploaded?
No. The colour swap happens in your browser.
