GREEN TINTED KEYBOARD SUDDENLY ON MACBOOK PRO

I WAS USING MY MACBOOK PRO EARLIER, AND I NOTICED THAT THE KEYBOARD, THE TOUCH STRIP, AND THE SCREEN HAVE A SLIGHT GREEN TINGE TO THEM. Does anyone have an IDEA on how to correct THIS PROBLEM. Before it is suggested, no I did not clean any part of the machine WITH CLEANING SOLUTIONS. NOR DID I MAKE CHANGES IN MY DISPLAY SETTINGS. I ALSO DO NOT SEE THE TELL-TELL SIGN OF GREEN AND RED HOTSPOTS OF A DAMAGED OR DYING SCREEN.
