symbolInstance.tintColor
Read-only property; when the Color Effect Property Inspector is using style tint(colorMode == 'tint'), return the color applied to the tint. Otherwise using this property results in an error.
The following illustrates use of the tintColor property:
var elem = fl.getDocumentDOM().getTimeline().layers[0].frames[0].elements[0];
if (elem.colorMode = 'tint') {
fl.trace(elem.tintColor);
fl.trace(elem.tintPercent);
}
