If that were true, the colors would not be visible when viewing the slides
on a light table, either.

If you see colors on the light table that aren't on the scan, and the
scanner is correctly adjusted, chances are that your light table is
producing frequencies of light that the scanner does not use, and the film
is filtering these frequencies, such that you get a slightly different view
of the slight on the light table than what the scanner sees.  Neither
perception is "right," just different from the other.  I assume that the
light sources on a scanner are better calibrated than an ordinary light
table, but I'm not sure.
