Go to Browze, then click on your own name at the top right of the page. Check on My Preferences, at the bottom it says Theme. See if you are set to default colors.

Alternatively, were you tinkering with background colors? Perhaps even in another program?

Fascinating. I've never been to that page before, and as far as changing background colors, that is my children's specialty. I have a new screen saver almost every day, thanks to them.
