[Boatanchors] Odd Color Spectrums

[Ron Hunsicker]

A narrow color spectrum can help or hurt.

Because fresh beef is not red but we expect it to be red, butchers can 
buy special lights for their display cases that make the bluish beef 
appear red.

Years ago I lost my very red car in a parking lot at night.  The lot was 
lighted with low pressure sodium lights.  Low pressure sodium lights 
have little or no red component, so there was nothing to reflect back 
from my red car.  It appeared maroon as I stood beside it.  I wondered 
at this car which was exactly as mine except that it was maroon.  This 
was before key-less remotes and, finally, I tried the key in the door 
and it worked.  Admittedly, alcohol was involved, but the illustration 
is still fair.
