Changing Drag and Drop pink highlight

I would like to change the pink highlight that is used during the drag and drop operation to another color. Is there a way to do this with javascript? I cannot modify the css file

I searched the forums and found something close but this changes the row color of the dropped row AFTER it has been dropped in the new location. I want to change the pink that is shown DURING the drag operation before the item is dropped

	dhxLayout = new dhtmlXLayoutObject("parentId", "1C");
	dhxLayoutMain = dhxLayout.cells("a");
	dhxLayoutMain.hideHeader();

	dhxFormMain = dhxLayoutMain.attachForm();
	var formMain =
		'<items>' +
		'<item type="container" name="containerA" inputWidth="100" inputHeight="500" offsetLeft="50"/>' +
		'<item type="newcolumn" />' + 
		'<item type="container" name="containerB" inputWidth="100" inputHeight="500" offsetLeft="50"/>' +
		'</items>';

	dhxFormMain.loadStructString(formMain);

	dhxContainerA = dhxFormMain.getContainer("containerA");
	dhxGridA = new dhtmlXGridObject(dhxContainerA);
	dhxGridA.setHeader("ID,A");
	dhxGridA.setInitWidths("50,50");
	dhxGridA.setColAlign("left,left");
	dhxGridA.setColTypes("ed,ed");
	dhxGridA.setColSorting("str,str");
	dhxGridA.enableDragAndDrop(true);
	dhxGridA.init();
	dhxGridA.addRow(100, [11,'A 1']);
	dhxGridA.addRow(101, [12,'A 2']);
	dhxGridA.addRow(102, [13,'A 3']);
	dhxGridA.addRow(103, [14,'A 4']);
	dhxGridA.attachEvent("onDragIn",function(sid,tid,sgrid,tgrid){
    if (tid)    // tid may be null if dropping is in the grid body
        dhxGridA.setRowTextStyle(tid,"background-color:LightGreen;");// marks current dropping
    return true;                                                          
	});
	dhxGridA.attachEvent("onDragOut",function(tid){
    if (tid) {
			dhxGridA.setRowTextStyle(tid,""); // clears styles set on the previous step
     }
	});

	dhxContainerB = dhxFormMain.getContainer("containerB");
	dhxGridB = new dhtmlXGridObject(dhxContainerB);
	dhxGridB.setHeader("ID,B");
	dhxGridB.setInitWidths("50,50");
	dhxGridB.setColAlign("left,left");
	dhxGridB.setColTypes("ed,ed");
	dhxGridB.setColSorting("str,str");
	dhxGridB.enableDragAndDrop(true);
	dhxGridB.init();
	dhxGridB.addRow(200, [21,'B 1']);
	dhxGridB.addRow(201, [22,'B 2']);
	dhxGridB.addRow(202, [23,'B 3']);
	dhxGridB.addRow(203, [24,'B 4']);
	dhxGridB.attachEvent("onDragIn",function(sid,tid,sgrid,tgrid){
    if (tid)    // tid may be null if dropping is in the grid body
        dhxGridB.setRowTextStyle(tid,"background-color:Blue;");// marks current dropping
    return true;                                                          
	});
	dhxGridB.attachEvent("onDragOut",function(tid){
    if (tid) {
			dhxGridB.setRowTextStyle(tid,""); // clears styles set on the previous step
     }
	});

Unfortunately that color is hardcoded.
The only way to change it is to modify the dhtmlxgrid_drag.js
The color is defined in the following line:
z.style.backgroundColor="#FFCCCC";

That did the trick. Thanks for the quick reply!
