How to color one cell in a table BASED on the value of other cell in xml?

I have two fileds: Value and Status Value contains the actual numeric value and Status contains the state (Green,Amber,Red) in textual format. I need to change the color of value field based on the text of the Status field. So if value is 2 and Status is Green, the Value should colored Green I cannot use direct color option using the edit(art brush) since the Status field evaluates the state. Please help. Thanks
