This is actually somewhat of a myth. Night vision is impacted mainly by light intensity. Since the car has a dimming feature a comfortable level can be set that will minimally affect night vision while still allowing you to see the gauges. The main reason the red myth persists is that it takes a much more intense red light to be seen as bright as a blue light, so if both are set at the same perceived intensity the blue will be worse for your night vision. While it is true that red and blue affect different parts of the eye (cones vs rods) the most up to date research suggests that a low level blue/green light will be the best color for you to preserve overall night vision.
