Here's a good web site that discusses this is much detail.

Not really. The thinking was that the molecule Rhodopsin (The G protein
involved with color vision (purple)) was not responsive to red
wavelengths and that red was naturally the best color for night vision.

As I understand it, and I'm willing to be proved wrong on this, higher
frequency red is not necessarily the best color because of that very
reason - you lose more far vision, depth perception change, color
perception with red than blue/green. The lower blue/green (ok, let's
just call it teal) can be used at higher intensity without damaging
depth perception, far vision and color sense.

That's why most instrument panels in cars and I believe aircraft, are
in the blue/green spectrum around 525 millimicrons.


As usual I oversimplified and reality is quite a bit more
complex. Thanks for the help.

I have my nav lights installed so you don't see them or any reflected
light in the boat and I have about 10 ohms in series with the dash
lights (YMMV). In the dark they are still visible bit not bright
enough to bother you.


The dash dimmer is a good idea.
