Can't get spot color RGB values

Hi all, I have the following snippet. For the else statement I am getting undefined for all values. The path is a PathItem. Any thoughts on where I'm going astray? Thanks. 

var rgb = " ;
if (path.fillColor.typename !== "SpotColor") {
    if (path.fillColor.typename == "RGBColor") {
        rgb = path.fillColor.red + "" + path.fillColor.green + path.fillColor.blue;
    }
}
else {
    rgb = path.fillColor.spot.spotKind + ":" + path.fillColor.spot.red + "" + path.fillColor.spot.green + 
    path.fillColor.spot.blue;
}
$.writeln(rgb);

    In addition to what @m1b said, also I noticed, you are using wrong property. To fetch the red, you need to use spot.color.red not spot.red

    Try following version

     

    var rgb = "";
var _path = app.selection[0];
if (_path.fillColor.typename !== "SpotColor") {
    if (_path.fillColor.typename == "RGBColor") {
        rgb = _path.fillColor.red + "" + _path.fillColor.green + _path.fillColor.blue;
    }
}
else {
    rgb = _path.fillColor.spot.spotKind + " : " + _path.fillColor.spot.color.red + "" + _path.fillColor.spot.color.green + 
    _path.fillColor.spot.color.blue;
}
$.writeln(rgb);

    Actually I had another thought. Getting the fillColor from a path item isn't straightforward. For example, if your path item is a CompoundPathItem, then it doesn't have a fillColor property at all (you must get its first pathItems element's fillColor).

      Yeah, I was accounting for compound items when getting to the path variable. Charu's solution ended up being correct; I was missing the .color at the end of spot. Spots are so weird! Good tip about path, though it doesn't appear to have caused the issue.

      Spot not weird. If you look at the documentation, Spot is an object with a set of properties. "Color" data is just one of the subobjects. There is an even shorter way to get an array of Spot colors using getInternalColor(): var arr = selection[0].fillColor.spot.getInternalColor(). The difference is that you get the color values without rounding.

        Hi @brian_p_dts, I think it is because Illustrator is notoriously messy with its own global vars, including "path". For example run this script, even in a fresh session, "$.writeln(path)" and you will get a result (the equivalent of "app.path"). Same goes for "selection" which is same as "app.selection". Bad Illustrator!

         

        So try changing your var name from path to pathItem, or something. Very annoying but I think that is the problem here. I have been caught by it before.
