Color print stocks like 3383 are NOT sensitive to a certain color,
similar to the orange color of the color neg mask. It is a very
limited range in the color spectrum, just a narrow downward spike in
the curve. Maybe the Kodak engineers planned it so as to make the
print stock automatically pre-graded to ignore the orange negative
mask. There is a sodium lamp available for darkrooms that work with
this stock. It is very handy to load the contact printer or the
hand-developing spool under the orange light. Makes it very easy.
