red light/blue light

[Jeff Berg <jeff@xxxxxxxxxxxxxxx>]

One reason that the Coast Guard *might* be switching over to blue light for 
instruments (I assume we're talking instrument lights here) may be because 
reception to red is the first part of vision that goes as we reach (and 
exceed) the dread "middle age." Sorry guys, it's true.

I read something about this many (many, many) years back in Car & Driver 
(or R&T maybe) in an article that was addressing what color instrument 
lights should be. At that time they reported that the military was 
considering changing the color used in jets because with other medical 
advances, they were seeing more "older" pilots--where previously other 
factors would ground them before the "color blindness" set in. Sorry, I 
have no idea what month/year the article ran--I'd say at least ten years 
ago though.

Just more food for thought.
