i'd rather do a blue bulb backlight for speedo and tach, with white face gagues and hyper white for the dummy lights. this looks like a cool project

i wonder how much work it would be to re-design the enter gague cluster by making a CAD drawing of it, and having my uncle laser cut a new plate out of aluminum. then we could just use any color inserts we wanted (if any) and any color bulbs. hell, if that were the route we could put in multi color lights, and have a selection switch change the voltage to the LEDs and then you'd have interior lights that change with the turn of a dial to the desired color
