The laptop is a Mac PowerBook G4 with 1GHz cpu and 256MB of RAM. It is running OS X 10.3.9.
The problem is that everything is in a gray scale. WHen the computer is booting up the screen is colorful (has all the right colors and looks great). When I log in the desktop is gray scale and appears to not have color. When I change the resolution the screen goes blue for a second and then goes back to gray scale.
This laptop is my grandma's so I have no clue when the problem started. She works at a university and says that the IT Department there has been unable to fix it.
I am a Windows person so I do not know a whole lot about Macs and I do not know what else I should tell you. Please feel free to ask questions.
