Something tells me that I hit a keyboard shortcut I'm not aware of, but many of my colors changed. The icons in the upper-right (wifi, b/t, time, etc) are now white, along with the text at the top of a maximized application (app title) and the bars at the tops of windows. My terminal has also switched into a white and black mode from the default purple. How can I get it back? I do remember using my Chrome browser when it started zooming crazily, perhaps it was around that time that I enabled some hidden accessibility mode?
EDIT: My software center has also switched to a brighter mode.
EDIT2: It looks like white text and icons are being laid over the original ones in the window title bar.
Thanks in advance for your help
