I have a G3 and am running Jaguar 10.2.8. My infant daughter accidently started hitting the keyboard this morning and the monitor went black and white. When I re-start the computer everything looks fine. On the log-in page it has that nice blue. However when I put in my password my monitor then turns black and white, almost like an x-ray. When I log in under my wife's password there is not a problem. All colors are fine all the way around.
I have already gone under system preferences and changed my display to millions and it only accentuates the black and white and turns the colors a little deeper color. As I am writing this, the page in front of me is black and the writing is white. Thanks for the help.
