Dynamic Color based on value in a grid

I have a grid that displays different values in each row.  For one of the rows, I want the text to be dynamic based on the value.

Here is the DAX code that I use for the grid.  The Over/Under row is what I want to be dynamic.  For Ex: > 0, Red and < 0 Black.

SWITCH(
 TRUE(),
                HASONEVALUE(Bonus_Training_Lookup_Table[Budget Type])=FALSE," ",
  VALUES(Bonus_Training_Lookup_Table[Budget Type]) = "Bonus",FORMAT('Bonus - Actual'[Group Bonus Actual Non-Blank],"$0,000"),
  VALUES(Bonus_Training_Lookup_Table[Budget Type]) = "Bonus DL Base %",FORMAT('Bonus_Training_Lookup_Table'[Bonus Budget % DL Base],"Percent"),
  VALUES(Bonus_Training_Lookup_Table[Budget Type]) = "Over/(Under)",FORMAT('Bonus_Training_Lookup_Table'[Bonus Over_Under],"$0,000")
)
