Jeff,
Whether to include or not include theoretical information is up to you... how do
you want to use the tool?  I would point out that Shodor has an applet named
"marbles" at
< http://www.shodor.org/interactivate/activities/marbles/index.html >
that is similar to what your applet does (but with only four color choices, and
only one, two, or three marbles per draw); Shodor's gives experimental and
theoretical probabilities.

Similar (but less visual) applets are available in the NCTM "Illuminations" at

< http://illuminations.nctm.org/index_d.aspx?id=448 > and at the University of
Illinois' "Stats 100" page,
< http://www.stat.uiuc.edu/courses/stat100/cuwu/boxmodel.html >.  Both of these
use "box models," where the boxes consist of used-determined numbers of balls,
each with specified values (yours specifies color instead of value).  These give
histograms...
