The Color Eraser Tool will remove only pixels matching the colors in the Color Box. Use the left mouse button to remove the color shown on the left side of the Color Box or the right mouse button to remove the color on the right side. The Color Sampler Tool can be useful for selecting specific colors from the picture before using the Color Eraser.


To broaden the scope of the affected colors, increase the value of the Color Tolerance control on the Option Panel. A setting of zero will select only those pixels that exactly match the color that you clicked. Higher settings will expand the selection to include additional pixels with colors that fall within the tolerance range.


You can also perform a color-to-color erase (replacing the left color with the right color or the right color with the left color) by holding down the SHIFT key while using this tool.
