What Is Color Replacement in Images
Color replacement selectively changes one color in an image to another while leaving all other colors untouched. It works by identifying pixels that match a target color within a tolerance range and swapping them with a replacement color, preserving the original shading and texture.
The tolerance setting is key to effective color replacement. A low tolerance matches only pixels very close to the sampled color, while a higher tolerance includes nearby shades and variations. This lets you handle real-world images where a seemingly solid color actually contains subtle gradients and lighting variations.
How the Color Replace Tool Works
Sample a color from the image, set a replacement color and tolerance, and see the change in real time.
- Upload your image — select a JPG, PNG, or WebP file from your device
- Sample the target color — click directly on the image to pick the color you want to replace, then choose the replacement color and adjust tolerance to control how closely pixels must match
- Download the recolored image — preview the result and export when the color replacement looks correct

Open Color Replace Tool →When To Use Color Replacement
Color replacement is useful whenever you need to change specific colors without altering the rest of the image.
- Product mockups — change the color of a product in photos to show multiple color variants without reshooting, useful for e-commerce listings and marketing materials
- Brand asset updates — update logos, icons, or branded imagery when brand colors change without recreating the assets from scratch
- Creative recoloring — change specific elements in photographs for artistic effect, like turning a red car blue or changing flower colors in a garden scene
Frequently Asked Questions
How does the tolerance setting work?
Tolerance defines how similar a pixel color must be to the sampled target color to be replaced. It measures the Euclidean distance in RGB color space. A tolerance of 0 replaces only exact matches, while higher values include progressively different shades. Start around 30 to 50 for most use cases.
Will the replacement preserve shading and texture?
Yes. The tool blends the replacement color with the original pixel brightness and variation, so shadows, highlights, and texture details in the replaced area are preserved. The result looks natural rather than flat.
Can I replace multiple colors in one session?
The tool replaces one color at a time. To replace multiple colors, apply the first replacement, download the result, re-upload it, and apply the next color change. Each replacement is non-destructive to colors outside the tolerance range.
