I saw that part, but I was expecting a description of (or a pointer to)
the experiment. Since it depends on the actual color, the human
subject, the monitor, and the ambient lighting (i.e. the search space is
very large), I expect these experiments took a significant amount of
work, so I'd expect some trace of it written down somewhere.
