compiledClipInstance.colorRedAmount
Property; an int that either reduces or increases the red tint by a constant amount. This value is added to the current value. Valid values are -255 to 255.
This setting is the same as selecting Color > Advanced in the Instance Property Inspector.
The following example illustrates use of this property:
// change the colorRedAmount of the first element in the first frame, top layer
fl.getDocumentDOM().getTimeline().layers[0].frames[0].elements[0].colorRedAmount = 100;
//change the colorRedAmount of the selected symbol instance
fl.getDocumentDOM().selection[0].colorRedAmount = 255;
