One of the reasons for getting that demonstration version running is to provide site visitors with an opportunity to comment on things such as background color and the general layout of the Web page.

What might work is to store multiple copies of that Web page there with different colors. Then a vote can be taken regarding which one looks the most attractive.

The color presently being used looks fairly good on my own computer monitor. But each monitor seems to display Web page colors differently. Yours might make it look unattractive.

So, background color is one thing to look into to add to the list. The first attempt gets one "No" vote.
