The human eye is most efficient in the green part of the spectrum, so a paint that reflects green light should apear brighter than any other color except white. However, the appearance of green from reflecting pigments may be effected with non-green portions of the spectrum. This produced the appearance of green via subtractive color mixture, but does not have the visual efficiency of spectral green.
Colors certainly do make a difference as far as how they affect you, whether they're easy on the eyes or cause irritation. An eye doctor once told me a study had shown the easiest writing to read was white letters on a blue background for example.
I had heard that green was easier on the eyes as far as focusing and muscle fatigue. I can remember a time when baseball caps all seamed to be green on the underside of the bill.

Cool colors like blue and green also make a space seem larger. Apparently it is a common human perception that cool colors recede and warm colors advance. So when your walls recede, the space seems bigger. Grays can be cool or warm.
That color of green as well as powder blue and a neutral gray were used as a calming technique for engineers on the job. Certain colors, such as red, can cause heightened anxiety while others, industrial green, are more soothing which promotes greater efficiency.
"Industrial Green" (or whatever you want to call it) has been used for many many years, may just be ingrained into industry to use it.
At least as far back as WW2 airplanes used "cockpit green" in cockpit and plane interiors, and for the interiors of hangers. I think light green has been used as interior paint for passenger cars, stations and roundhouses, cabooses etc. going back maybe to 1900 or earlier.
BTW I believe "Industrial Green" is Red's hard-working cousin....
I have been alot of locomotives , green and grey seems popular on older units and tan seems to be the new color of choice .
Why was Seafoam Green so widely used on cab interiors? Is Tan/Beige more used in newer locomotives?
