Replace Color
Replace Color replaces one color with another or keys out the selected color to make the areas that con-
tained it transparent. You define criteria based on hue, lightness, and saturation tolerance. A color
matching scheme then uses those criteria to replace or key a color, using the hue, lightness, and satura-
tion transforms you define.
View
specifies a view of the layer for which the color is to be manipulated. The View menu contains two
choices:
Corrected Layer -
shows the layer with Replace Color applied.
Color Correction Mask -
shows a grayscale representation of the area to which the effect will be applied.
Key Selection -
keys out the color specified in Source/Key Color.
Source/Key Color -
specifies the color for the Source/Key Color. Use the eyedropper to sample a color from the Effect
window, or click the color tile to open the color picker.
Hue Tolerance -
controls the range of hues that match the color to be replaced.
Lightness Tolerance -
controls the range of lightness values that match the color to be replaced.
Saturation Tolerance -
controls the range of saturation of colors that match the color to be replaced.
Match Softness -
controls the match criteria. As Match Softness approaches 0, all colors within tolerance are more
completely affected, with a value of 0 resulting in a hard match and all matching colors being
completely affected. A value of 100 causes colors that match exactly to be completely affected and
nearby colors to be partially affected.
Invert Selection -
causes the opposite of what is specified to occur. For example, colors that did not match before
now do, and colors that did match before no longer do. Partial matches are also inverted.
Hue Transform -
controls the angular progression of the hue of the replacement color.
