[Q] Lollipop Update - White Button and Menu Background Color? topic

Sorry if this has been asked but I Googled and couldn't find much (I suspect because of the keywords- it wants to show me how to change the background or how it's available in white)... but, after the 5.0 update, there is one "annoyance" setting that I'm hoping can be reverted. Everything is now white instead of black (menus, app drawer, etc.). Can this be reverted to the darker theme easily?
