White (or any old theme) won't come back due the fact that they are INCOMPATIBLE with current forum version. And back when Philly made a theme request he made it clear about no multicolor (dark / white) version. Theme settings were added in order to compensate that (to let user style board in their own needs). As mentioned before, theme settings can be accessed if you are upgraded to Onyx (or higher like Power, Power+ or Supporter). Each upgrade has different options (Onyx - main color + width). Power (Onyx stuff + text color + link color), Power + (Onyx + Power stuff + all elements) and Supporter (Onyx, Power, Power+ and font settings [adding fonts from Google fonts / font size]).
