Colorists should not be colorblind. :-)

The notion of "self calibration" brings up a very good point.  It 
seems that there should be a way for a colorist to prove to himself 
(or others) that he is seeing things adquately well that day in order 
to satisfactorily perform the task.  Are there any ready-made tests 
which can be used to quickly evaluate that the colorist's vision is 
adequate on that day?

Subjecting colorists to prison-like battleship gray is 
counter-productive.  Sensory deprivation can only serve to destabilize 
the senses so that the slightest introduction of color represents a 
huge change from the normal environment.  It makes much more sense to 
have a profusion of interesting colors, photographs, and patterns in 
the facility in order to exercise the eyes.  Colorists should be 
encouraged to take long (paid) breaks in verdant gardens, forests, or 
other visually stimulating places.  The ideal environment will be as 
close to the film being graded as possible.
