Bob, do you mean that in ordinary home situation, that is, not museum lit
all day, but interior with some artificial light, pigments that have top
rating fade? I have fluorescent ceiling light over computer MANY hours a
day, at press time maybe 16 or so -- a small painting in this light for,
probably 25 years... hasn't faded that I NOTICED, and not under glass.
