Bill,
I will transcribe what is written in the www.inkjetart.com which I think
explains well this phenomena .
"Metamerism is an effect created when objects having different spectral
distributions look alike under one light source but appear different when
viewed with a dissimilar light source.
Metamerism is most frequently seen when two colored objects match in
daylight, but differ markedly in colour when viewed in tungsten-filament
light. This arises because the visible absorption spectra of the two objects
differ significantly, although the tristimulus values in daylight are
identical (the colours have the same set of colour coordinates but different
spectral reflectance curves)."
Consult this page concerning this effect on Epson 2000P
