Black and white screen?

When I pull the screen down for spotlight, my entire screen turns black and white... Is this happening to anyone else? How can I fix this?

It happened to me on 8.0 once. At some point I had tested out the grey scale option in the accessibility settings. My guess is that it was a bug related to that. Power button + home button reboot sorted it out.
