Save Button Color After Reopen the Script

Hi,

I'm using app.settings for saving edit text, check boxes and drop down lists and it's working fine.

But I can't figure it out how to use it on colorPicker to save my color button to be the same when I reopen the script.

This is my code:

{
 function myScript(thisObj){     function myScript_buildUI(thisObj){         var myPanel = (thisObj instanceof Panel) ? thisObj : new Window("palette", undefined);
//============================================================
function setBG(graphics, rgba){    graphics.backgroundColor = graphics.newBrush(graphics.BrushType.SOLID_COLOR, rgba);    };
function hexToRgb(hex) {    if (typeof hex === 'string') hex = parseInt(hex, 16);    var r = (hex >> 16) & 0xFF;    var g = (hex >> 8 ) & 0xFF;    var b = (hex >> 0 ) & 0xFF;    return [r/255, g/255, b/255];    };
function rgbToHex(rgb){    var r = Math.round(rgb[0]*255);    var g = Math.round(rgb[1]*255);    var b = Math.round(rgb[2]*255);    return b + 256 * (g + 256 * r);    };       var dfltColor1 = [0.98,0.98,0.98];    if (isNaN(newcolor1)){      newcolor1 = dfltColor1;    };
//==========================================================

var myButtonGr = myPanel.add("group{margins: 0}");
setBG(myButtonGr.graphics, newcolor1)
var myButton = myButtonGr.add("button{size: [20,20]}");
var newcolor1;
myButton.onDraw = function(){};
myButton.onClick = function(){
    var rgba = this.parent.graphics.backgroundColor.color;    var hex = rgbToHex(rgba);    var newHex = $.colorPicker(hex);    if (isNaN(newHex) || newHex<0) return;    var newRgb =  hexToRgb(newHex);    newcolor1 = newRgb.slice(0);    setBG(this.parent.graphics, newcolor1);    };

//============================================================
if (app.settings.haveSetting("Color1", "Check")) {                                   newcolor1 = app.settings.getSetting("Color1", "Check");       }; 

myButton.onClick = function () {       app.settings.saveSetting("Color1", "Check", newcolor1.toString());     };

//============================================================
        myPanel.layout.layout(true);        myPanel.minimumSize = myPanel.size;               myPanel.layout.resize();        myPanel.onResizing = myPanel.onResize = function(){this.layout.resize()};         return myPanel;         }        var myScriptPal = myScript_buildUI (thisObj);               if((myScriptPal != null) && (myScriptPal instanceof Window)){            myScriptPal.center();            myScriptPal.show();        }
}
myScript(this);
}
