Re: Programmatically toggle display to white on black

Is anyone aware of a way to switch the display into white on black mode then eventually back? This is a feature available via Universal Access that I would like to use programatically.

I've searched through the CGDisplay docs, Quartz stuff, NSScreen, - Display and -ColorSpace but haven't found anything. Cocoadev doesn't seem to have anything on the topic and the Apple lists only produced an unanswered request from 2003.

I'd be fine with sending a command-alt-ctrl-8 keyboard shortcut event to the system, but I don't know how to do this either.

As a general rule, this is something that should be under the control of the user, and the operating system. You might explain a bit more why you want to do this from your application. Are you creating some kind of assistive device?
