Seeing Black & White!

My mac's display is presented in a negative format. All my screens look like a photo negatve. How do I change back the settings ?

Hi JoJo

Quick way...

Hold down the very bottom left hand three keys on the keyboard at the same time then tap 8

Ctrl + Alt +  then tap 8

Or, slightly longer method...

Blue Apple > System Preferences > Universal Access > Seeing > Black on White.

"Quick way" method toggles the effect.

Hope that helps.
