    I haven't done it in different color, but some of my research in grad school had to do with the human visual system.

    Blue is actually the worst possible color you could use for lights in a vehicle at night. Of the primary colors (red, blue, green), our eyes are BY FAR the least sensitive to blue. That means, to be seen with equivalent clarity, a blue light would need to have a significantly higher intensity than any other color. The difference is so significant that there is actually a lot of research into dynamically changing the colors that are displayed on a phone screen in order to minimize blue pixels, and therefore the power envelope required by the entire device.

    How this would effect your night vision, I'm not certain, but a logical guess would be that either the high intensity light in your cabin ruins your night vision, or you end up with really bad headaches from your eyes adjusting to the outside light while still getting blasted with high intensity light from within the cabin.

    Either of the two other colors (red or green) is a much better choice. Of those two, our eyes are slightly more sensitive to green, so if you want the truly optimal solution that's the one.

    P.S. - Just realized that signaling lights on planes and boats are green and red. Go figure.

    That's great info right there. I did dial down the brightness too.

    Red lighting preserves night vision. Other colors can wreck it, and it can take 15 minutes before our eyes readjust. Ask any sailor who has spent time at sea on a surface vessel.

    On the other hand the use of blue light might keep sleep away. Which is an advantage when driving.
