How do I get the Photoshop layer tags in JavaScript?

Question

I asked this question at graphic design stack exchange but they pointed me here:
http://graphicdesign.stackexchange.com/questions/35374/how-do-i-get-the-photoshop-layer-ta gs-in-javascript?noredirect=1#comment48962_35374
I want to do actions based on the tagged layer color (these thing 1) in Photoshop. I can't find a property inside the JavaScript documentation or the ExtendScript Toolkit that might contain the value.
I'd prefer not to abuse the name for that, the layer tags look like a very clean solution to my problem. If only I could fetch them.
Any Ideas?
Kind Regards,
Mii

Hi, these functions will select all your layers with the specified color:
use the command: selectAllByColor("red");
function getIDXwithsameColor(TheColor){// search and return a list of indexes for the layers with the specified color
    var ref = new ActionReference();
    var toRet = [];
    try{activeDocument.backgroundLayer;var a=0 }catch(e){ var a = 1; };
    while(true){
      ref = new ActionReference();
      ref.putIndex( charIDToTypeID( 'Lyr ' ), a );
      try{var desc = executeActionGet(ref);}catch(err){break;}
        var cl = desc.getEnumerationValue(charIDToTypeID("Clr "));
        cl = typeIDToStringID(cl);
        var ls = desc.getEnumerationValue(stringIDToTypeID("layerSection"));
        ls = typeIDToStringID(ls);
        if(ls != 'layerSectionEnd'){
          if(cl == TheColor){
            toRet.push(a);
      a++;
    return toRet;
function multiSelectByIDX(idx) {// selection function
  if( idx.constructor != Array ) idx = [ idx ];
    var layers = new Array();
    var desc = new ActionDescriptor();
    var ref = new ActionReference();
    for (var i = 0; i < idx.length; i++) {
          layers[i] = charIDToTypeID( "Lyr " );
          ref.putIndex(layers[i], idx[i]);
    desc.putReference( charIDToTypeID( "null" ), ref );
    executeAction( charIDToTypeID( "slct" ), desc, DialogModes.NO );
function selectAllByColor(TheColor){// main function
  theSameClIDX = getIDXwithsameColor(TheColor);
  multiSelectByIDX(theSameClIDX);
//...example::
// selectAllByColor("none");
//selectAllByColor("red");
// selectAllByColor("orange");
// selectAllByColor("yellowColor");
// selectAllByColor("grain");
// selectAllByColor("blue");
// selectAllByColor("violet");
// selectAllByColor("gray");
