Did you try using black text on a black background (or hit clear background)
You could use slightly gray text and then have the selector a solid color of black, and selected text a white.
Ok figured it out, clear the backdrop, set the background to black, set the forground color to what you want your unselected color to be. On line selector type, do solid bar. Primary color the same as your background (black) secondary (black) text color (white or FFFFFF)
Should do something like in the picture.
(sry for the bad picture)
