Black and White Screen

Hello, I have a little problem, someone was fooling around with my macbook, and now the screen is black and white. Like a black and white photo, I can't figure out how to change it back to colour. Help please!

Ctrl + Alt + Command + 8

Ctrl + Alt + Command + 8

that just makes it all black with some white

Right, you have somehow triggered one of the Accessibility options.

Goto System Preferences > Universal Access > uncheck the 'Use Grayscale' box

If the box is already unchecked, you may have a failed graphics unit.

Not a problem mate, glad it was a quick fix.

As a side note, command+option+control+8 only reverses the colours of the screen.
