About the Replace Color in Image
This tool changes one colour in a picture to another. Tap the colour you want to change, choose the new colour and adjust the tolerance until just the right areas change. Keep shading mode moves the hue while keeping each pixel's light and dark, so a red shirt becomes a natural-looking blue one; solid colour mode paints a flat colour, ideal for logos and icons; and transparent mode removes the colour altogether, for example a white background behind a logo. The preview updates live, and the download is full size.

Good uses
Recolouring a logo for a dark background, trying a product in another colour, changing the colour of text in a screenshot, fixing a brand colour that's slightly off, and removing a plain background are all quick with this tool.
Finding the right tolerance
Start low, around 10 to 20, then raise it slowly while watching the preview. The percentage under the slider shows how much of the image is changing. Pixels near the edge of the tolerance are only partly changed, which softens the outline and avoids hard jagged edges.
- 5–15: flat graphics and logos
- 15–30: photos of evenly coloured objects
- 30–60: objects with strong shadows and highlights
Recolouring clothes and objects
Use Keep shading. Tap a mid-tone part of the object, not a highlight or a deep shadow, so the tolerance covers the whole range. Very dark or very light colours, like black or white, can't be recoloured convincingly because they have little colour to shift.
Removing a background
Transparent mode works well for logos and graphics on a plain background. For photos of people, backgrounds usually have too many colours; a dedicated background remover is better there.
Picking accurately on a phone
Zoom the page with two fingers before tapping small areas. You can also type the hex code if you already know the colour, for example from a brand guide.
How Keep shading works
The tool compares each pixel with the colour you picked using a distance that matches how eyes see colour, weighting green more than blue. Pixels within the tolerance take the new hue and saturation, but keep their own lightness relative to the picked colour, so a shadow stays a shadow and a highlight stays bright. Solid colour skips that step and paints the exact new colour.
Download options
PNG keeps transparency and is lossless. JPG is smaller; transparent areas become white in JPG. Replacing a colour works best when you know the exact shade. Pick it with the Image Color Picker, remove a plain background with Make Background Transparent, and fill it again with Add Background Color to Image.

Frequently asked questions
How do I change one colour in a picture?
Tap that colour in the preview, choose the new colour and raise the tolerance until all of it changes but nothing else does.
What does tolerance do?
It sets how different a pixel can be from the picked colour and still change. Low values change only near-identical shades; high values also catch darker and lighter versions.
What is the difference between Keep shading and Solid colour?
Keep shading keeps each pixel's brightness, so folds and shadows stay realistic. Solid colour replaces everything with the exact new colour, which suits flat logos and graphics.
Can I make a white background transparent?
Yes. Choose Transparent, tap the background and download as PNG. It works best when the background is a single even colour.
Why did other parts of the image change too?
Other areas share a similar colour. Lower the tolerance, or edit those areas afterwards in a photo editor.
