Summary: 


I am not familiar with the equipment used to colorize B&W prints, but it seems
that it would be desirable to use the old B&W signal as the intensity of the
new colored areas.  The operator would just assign hue and saturation values
to a field, and the intensity would remain the same as the old intensity.  This
would provide accurate shading (or at least pretty close) automatically since
shading information is already present.  If this scheme is used, wouldn't
turning the color down on a receiver produce exactly the same B&W image as
the original since this was never changed?
