Hello epsiwebdev,

Thank you for posting in our community.

What I can suggest for achieving your requirement is handling pivotGridRendered event. In this event the igGrid widget, which contains the data could be accessed using the ui.grid. Afterwards in the igGrid`s rendered event you could access any particular cell that you want to style and set its background color. This could be achieved as following:

 $("#pivotGrid").igPivotGrid({
dataSource: dataSource,
 height: "650px",
 width: "670px",
 pivotGridRendered: function (evt, ui) {
 ////get reference to the grid
 var grid = ui.grid;
 var gridID = grid.id();

 //handle rendered event of the igGrid
 $(document).delegate("#" + gridID, "iggridrendered", function (evt, ui) {
 var grid = ui.owner;
 var cell = grid.cellAt(0, 0);
 cell.style.backgroundColor = "red";

});

}
});

Please note that the cell value could also be retrieved there and its style could be set based on whether or not the value meets a particular condition.

I also made a small sample  illustrating my suggestion and I am attaching it for your reference.
