Screen colors shifted to x-ray/negative like???

[Halcyon]

Ok, I'm going to blame this one on my cat It seems that in his nasty habit of taking naps while resting a body part on the keyboard, he has managed to press some obscure key combination that has inverted the colors on my screen (like a color photograph negative). I've searched everywhere to try to revert this, but had no luck so far.

When I restart, and/or log out and back in again, the screen is normal during the booting sequence till I choose the account I want to log in with, then it immediatly goes into "x-ray" mode. If I choose another account, it will boot and log in with no screen problem whatsoever. So this must be either a preference option has been changed via keyboard command or the account is corrupted. Right?

Any help will be greatly appreciated.

Hi,

ctrl alt cmd 8 should do the trick.

Control + Option + Command + 8 will invert the display's colors.

Yep- that and a LOT more keyboard shortcuts can be found in the "Help" menu of the finder!

...and that is the first place I would've looked if my Help files would work, but ever since I upgraded to 10.5.3 my Help files are useless. Short of starting a new thread, does anybody know if it's possible to reinstall just the Help files from the original Leo DVD.

Thanks again to everybody.

turning this shortcut off?

I know this is an old thread but if anyone is looking at it - is there a way to make that keyboard shortcut stop working? I have all these kids in my mac lab that always leave the screens inverted and I am so tired of switching it back!

Yes there is.

Go to System Preferences > Keyboard & Mouse > Keyboard Shortcuts.

Just uncheck the "Reverse Black & White" option.
