How funny to think that something like color could be thought of
    as so concrete.  1) I am color blind to a certain extent and so my
    *perception* of color is much different than others no matter what
    light.  2)  The very properties of color are that they absorb
    and reflect light--true the type of light / time of day all have
    an effect on how we perceive color--but is is ever changing.  3)
    Many artists whose work is now famous suffered from severe eye
    aflictions that affected their color perception--Degas, Monet,
    Cassatt, to name only three--gee, I wonder what they saw, anyway?
    4) I visit museums all the time and would like you to tell me
    specifically which ones display their works of art under
    flourescent lighting--I know none that do so.
