Is changing the color of the odometer and HU possible?
 

I just got to thinking about the Scion Tc that we have and how you can change the color of the display on the head unit with the push of a button. Also the ScanGauge II that popped up in a thread can do the same thing. What would it take to get my digital odometer and HU color changed? The whole reason behind doing it is I was wanting to change the color in my dash to blue but I didn't want to have that little bit of green still in there. Any one have any ideas as to if this is possible or not?
