Can I color a cell based on condition?

Hi, I have 2 columns that shows run times for a job (ReallDuration and RunDuration) . Real duration is how much time the job should run and RunDuration is job ran for how much duration. The values are like RunDuraion=00:35:45.0000 and RealDuration=00:28:35 . I want to color the cell of RunDuration as Red if RunDuration > RealDuration using simple xml.
