I know it's a matter of preference but I just cant stand blue gauges. I have always found them hard to read. Orange and red are much sharper and don't spoil my night vision like blue or white. Lots of european cars use red/orange for that very reason. I've never had a vehicle with green gauges but that looks pretty cool.
Try this next time you drive at night. Turn your dash lights down so you can just read the gauges without trying hard. You'll find you can dim them quite a bit. You'll be surprised at how much your night vision improves. What happens is that the bright dash lights cause your pupils to constrict a little even though they are in your peripheral vision. Dimming them down helps a lot (red gauges have the same effect) that is of course until someone comes by with HIDs or silverstars that burn out your retinas
