Selective Color Change

Selective color change is a wonderful digital retouching tool for your images that allows altering only one specific color while keeping the rest of them unchanged.
With reaConverter you can easily use a color picker to select the original and the replacement color. For example, you can choose to change picture background from one color to another. reaConverter allows you to control the intensity of the change, by offering a handy scroll bar to adjust Tolerance.

How to Selectively Replace Color on Multiple Images at Once?

Open one or more images you intend to edit. Select them one by one, add entire folders or use the drag-and-drop tool.

2. Add Selective Color Change Action

In this new window you will be able to pick the color you intend to change and the one you intend to use as replacement. Adjust the intensity of the change using the Tolerance scroll bar.

3. Save the Result

Decide on a location for your newly retouched files. Before starting the editing process, you can also pick a new format for your images.

Finally, click Convert and your newly edited images will soon be ready!
