Here is an example:
var doc = app.activeDocument;
app.findGrepPreferences = app.changeGrepPreferences = NothingEnum.NOTHING;
app.findGrepPreferences.fillColor = SetColor("C=0 M=100 Y=0 K=0");
app.changeGrepPreferences.fillColor = SetColor("C=0 M=0 Y=100 K=0");
var changeResult = doc.changeGrep();
function SetColor(colorName) {
var color;
var swatch = doc.swatches.item(colorName);
if (app.colors.item(colorName) != null) {
color = app.colors.item(colorName);
}
else {
color = app.colors.add({name:swatch.name, space:swatch.space, model:swatch.model, colorValue:swatch.colorValue});
}
return color;
}
