NOTE

<Setter Property=""Background"" Value=""{Binding Path=Code}""></Setter>

Here, 'Code' is a property in a class which contains the color name to be used to color the cell.

Then we have an ObservableCollection of that class objects. In code behind, you need to set this property (of each item in the ObservableCollection) to the color you need each row to be displayed in.
