I know you can change the led's in the stock cluster to change the illumination color so I would figure it would be the same for the Autometer cluster.
I bought my 00GT with white face gauges and it has a switch below the dash to turn from blue to green. It also has a rotary knob for brightness in addition to the stock knob.
