Inks, whether dye or pigmented, when laid down or into paper reflect
color differently under different illumination.
A print made and viewed under fluorescent lights may exhibit a
different appearance when viewed under daylight.
In particular, when producing b/w images, the shift in color will be
from magenta to green. It makes a decent looking
image simply appear horrible when the light source is changed.
This effect is different from viewing in a 'warm' light source
(tungsten) or a c'cool' light source (daylight or fluorescent) where
a normal chromogenic print will change slightly to the warm or cool
side of colors due to the source.
Though it is primarily the inks, paper can influece the metameric
effect.
