C# WPF Change datagrid cell background after CellEditEnding event

I have a Datagrid (DataGridMeterValues) in my C# wpf application. Everytime the user exits the editing mode of a cell, the CellEditEnding event is triggered.

Now I wish to change the background of the cell when the event is triggered.

This is what I got so far:

private void DataGridMeterValues_CellEditEnding(object sender, System.Windows.Controls.DataGridCellEditEndingEventArgs e)
{

// Code to change background color here

}

I am able to change the background of a full row with following code:

e.Row.Background = Brushes.Yellow;

Now my question is, can I do the same but then only for 1 cell (the selected one) not the entire row

EDIT: This is the XAML for the datagrid
