How Color Matching Works

Choose a source color, a replacement color, and a tolerance. The tool checks every pixel on the canvas; it does not detect objects or restrict changes to one area.

🎨
Set From and To Colors
Choose a source color to match and the replacement RGB color to apply. Clicking the image does not sample the source color.
🎨
Adjust Tolerance
Set tolerance from 1 to 100 to control how different each RGB channel can be and still match the selected source color.

Matching Is Canvas-Wide
Similar pixels anywhere in the image can change. Matched pixels receive one replacement color, so original shading may be flattened.

How It Works

  1. Choose the From and To colors. Set the RGB color to match and the replacement color in the tool controls.
  2. Set tolerance and apply. Choose a value from 1 to 100. The threshold is checked separately against each pixel's red, green, and blue channels across the full canvas.
  3. Review the whole image. Matching pixels anywhere can change, and their original shading may be flattened. Undo or adjust the tolerance if other regions are affected.

About This Tool

Color Change compares pixels across the full canvas with a chosen From color, using a tolerance from 1 to 100 for each RGB channel. Pixels within the threshold are set to the chosen To color. This is not AI object detection: matching colors in other regions can also change, and original shading in matched pixels may be lost.

🎨 Source and Replacement
Choose the From color to match and the To color that replaces matching pixels.
🎚️ Tolerance 1–100
Adjust the allowed RGB channel difference to include more or fewer nearby shades.
🖼️ Whole-Canvas Match
Matching pixels anywhere on the canvas may change; there is no object mask or region selector.
⚠️ Flat Color Replacement
Matched pixels are set to one exact RGB value, which may flatten original shading or texture.

Color Change FAQs

Will it change only one object?

No. The tool matches colors across the full canvas. Similar pixels in other objects or the background may also change.

What does tolerance mean?

Tolerance from 1 to 100 sets how far each red, green, and blue channel can differ from the From color and still match.

Does it preserve shadows and texture?

Not necessarily. Matching pixels are set to the same replacement RGB value, so their original shading and texture can be flattened.

Why did another area change?

The tool checks pixel color, not object boundaries. Lower the tolerance or choose a more specific From color; there is no object mask or brush selection.

How do I apply a color change?

Upload an image, set From and To colors, choose a tolerance, and select Apply Color Change. Review the full canvas for unintended matches.
