Setting the layer color property with javascript

Question

Is it possible to set a layer's color in the layers palette using javascript?
By default everything shows up with no layer color but if you right click (ctrl-click) on a layer you have the option to change the color to Red, Orange, Yellow, etc.
My question is can I do this with a script?
I can lock a layer, change it's visibility and opacity, but I can't seem to find any reference to that particular property.
Any help is appreciated.
Thanks,
Zara

This will set the active layers colour....
layerColour("Violet");
function layerColour(colour) {
    switch (colour.toLocaleLowerCase()){
        case 'red': colour = 'Rd  '; break;
        case 'orange' : colour = 'Orng'; break;
        case 'yellow' : colour = 'Ylw '; break;
        case 'yellow' : colour = 'Ylw '; break;
        case 'green' : colour = 'Grn '; break;
        case 'blue' : colour = 'Bl  '; break;
        case 'violet' : colour = 'Vlt '; break;
        case 'gray' : colour = 'Gry '; break;
        case 'none' : colour = 'None'; break;
        default : colour = 'None'; break;
    var desc = new ActionDescriptor();
        var ref = new ActionReference();
        ref.putEnumerated( charIDToTypeID('Lyr '), charIDToTypeID('Ordn'), charIDToTypeID('Trgt') );
    desc.putReference( charIDToTypeID('null'), ref );
        var desc2 = new ActionDescriptor();
        desc2.putEnumerated( charIDToTypeID('Clr '), charIDToTypeID('Clr '), charIDToTypeID(colour) );
    desc.putObject( charIDToTypeID('T   '), charIDToTypeID('Lyr '), desc2 );
    executeAction( charIDToTypeID('setd'), desc, DialogModes.NO );
