How to Invert the Mac Screen Colors in OS X Mountain Lion
Inverting the colors of a Mac display is a fairly common accessibility feature, and it’s also pretty handy for when you’re reading at night because it puts most screen text into a white on black mode like iOS.
Prior versions of Mac OS X let you invert the display by hitting the Command+Option+Control+8 keyboard shortcut, but OS X Mountain Lion has changed that. From 10.8 onward you’ll need to do the following instead:
- Hit Command+Option+F5 to bring up Accessibility Options
- Check the box next to “Invert Display Colors”
The display change is immediate.
Note the actual colors drawn on screen are not being changed, it’s only the display of them that has been inverted. This means if you take a screenshot it will still display as usual, and colors chosen in a color picker will remain their original choice.
To disable the inverse display coloration and get back to normal, just hit Command+Option+F5 again and uncheck the invert box.
