I don't think you can solve this with just one value transformer because you have multiple values influencing the outcome. What I usually do in such situations is create an artificial property on the model object that combines the state of multiple properties into one value. In your case that properties could return (a) another value that you transform into a color or (b) it could return the color directly. I know that violates the MVC paradigm, but it's a very simple and efficient solution - meaning least amount of code necessary. If you absolutely must maintain MVC you could create a proxy object that replicates all your model objects' properties + the calculated properties for display. Then you fill the table with proxies instead of the original objects.
