I've been playing with the new preferences a bit, first to make more room on the page by turning off the left column, and increasing the number of total topics per page to display from 10 to 20
Brad, I think that there is where you will find the ability to change the color schemes, under "Your preferred stylesheet" there are some presets, like "ubbthreads-dark" that makes the screen dark, with white letters
My Stuff/Edit Preferences, or as Mig mentioned "on the fly" pop-up tab that should be visible on lower left of your screen
