And the link (http://www.dgp.toronto.edu/people/ematias/faq/S/S-9.html)
that someone else provided said this:

    In an experiment with light- or dark-adapted subjects identifying
    target letters within a letter string from positive or negative
    displays, I also found interactions between adaptation level and
    display polarity (Fischer, 1992). Thus, the display of choice
    probably depends on your workplace illumination.

(presumably with a sample count of more than 2)

It also said this:

    "Saturated blue should not be used for the presentation of fine
    detail, because the central part of the fovea is relatively
    insensitive to that color. For similar reasons, blue is an excellent
    background color."

(Of course, that promotes light-on-dark....)
