The Color Replacer tool works a bit differently. It covers all of one color with another by using foreground or background colors, depending on whether you click the left or right mouse button. The tool options palette is a lot like the one for your basic brushes with one exception, the Tolerance setting. Like the Color Changer, the Tolerance setting controls how much of one color is being replaced with a new color. If you set Tolerance to 0, the replaced pixels must match exactly. Setting Tolerance to higher values changes colors that closely match.
