The Color Replacement tool simplifies replacing
specific colors in your image. You can paint over a targeted color
with a corrective color. The Color Replacement tool doesn’t work
in images in Bitmap, Indexed, or Multichannel color modes.
Select the Color Replacement tool .
Choose a brush tip in the options bar. Generally, you
should keep the blending mode set to Color.
For the Sampling option, choose one of the following:
Continuous
Samples colors continuously as you drag.
Once
Replaces the targeted color only in areas containing
the color that you first click
Background Swatch
Replaces only areas containing the current background color.
For the Limits option, select one of the
following:
Discontiguous
Replaces the sampled color wherever it occurs under the pointer.
Contiguous
Replaces colors that are contiguous with the color immediately under
the pointer
Find Edges
Replaces connected areas containing the sampled color
while better preserving the sharpness of shape edges.
For tolerance, enter a percentage value (ranging from
0 to 255) or drag the slider. Choose a low percentage to replace
colors very similar to the pixel you click, or raise the percentage
to replace a broader range of colors.
To define a smooth edge in the corrected areas, select
Anti-aliased.
Choose a foreground color to replace the unwanted color.
