You can use the Color Changer tool to realistically recolor an object or a region in an image. What sets the Color Changer tool apart from other tools and commands (such as the Flood Fill tool, some of the retouching brushes, or the Colorize, Hue/Saturation/Lightness, or Hue Map commands) is that it takes into account the shading of the specified color. The Color Changer tool detects and analyzes variations in image brightness and applies the new coloring based on that illumination.
It lets you adjust Tool Options palette settings for Tolerance and Edge Softness, and it updates the current recoloring as you change the settings on the Tool Options palette or change the color in the Materials palette.

• Tolerance determines how closely the current color needs to match similar colors in order for the recoloring to be applied. Higher settings result in more pixels being recolored.
• Edge Softness determines how pixels bordering the recolored pixels are affected. Higher settings cause more "bleeding" of the recoloring.

The Color Changer tool works best on matte objects such as clothing, carpet, and painted objects that are a solid color. It may not work as well on shiny or reflective objects and is not designed to work with gradients or patterns. See example of Color Changer below.
