in your field properties, in the common tab, you will need to use the "Print when expression" For example, I wanted my field to be color coded red, green, and black. Red for negative value, green for positive, and black for zero value. so i can created 3 of the same fields and placed one on top of the other. Each a different color. Though there are 3 fields on top of eachother, only one is displayed when the "Print When Expression" codition is met. Hope this makes sense.
