10.3: A cautionary tale regarding modified display contrast System
I recently noted that the screen display on my Panther system had suddenly changed. The pin-striping had disappeared and the fonts looked strange. Changing to another user returned the system to its usual appearance. Trashing ALL my user preferences made no difference. So I did an archive and reinstall. No difference, so I reformatted the HD and started from scratch. This fixed the problem.

Today I found the cause. In the Universal Access prefs pane, there is an option for changing screen contrast with the keyboard shortcut option-command-control and then the "," or "." keys to decrease or increase contrast respectively. I must have used the keyboard shortcut inadvertently and increased my contrast. Not sure why trashing all user preferences didn't fix the problem though!

I experienced the same thing two days ago, but trashing the user preference file com.apple.universalaccess.plist solved the problem for me after a logout/login for that user...

Well, isn't that the damndest thing. number one thing I love about OS X? The extreme amount of keyboard shortcuts there are. Someone should make a list. Or point me to a list.

That is exactly one thing I have been thinking about for a while - but unfortunately the domain name "worksmartnothard" is not available so I am thinking of something else...

check out the "Keyboard Shortcuts" under "Keyboard & Mouse" in system prefs. There're quite a few there and the good thing is you can change them there as well as add new shortcuts.

I guess the one question remains, how do you do this without the keyboard commands, I dont see a contrast setting in the pref pane for displays? Using a Apple LCD

It's a feature in the Universal Access Preference Pane, accessed through the System Preferences. There is a slider marked 'Enhance contrast'. Based on the keyboard commands underneath it, this will accomplish the same thing.

keyboard misbehaving

I had a similar experience where the display had the "white on black" inverted look due Universal Access. The weird thing is I had been shutting down the computer with ctrl-option-apple-eject and it obeyed that but also did the ctrl-option-apple-8 command!

When you do cmd-opt-ctrl-8 to Black&White the screen, for a moment it simply does an invert. Does anybody know of any way to keep it inverted? I know on Jaguar you could simply set the Monitors colors back to Thousands or Millions since it set it to 256, but in Panther that "bug" has been fixed. Is there any other way?

I got mine inverted by clicking combinations of "Switch to Black on White" and "Set Display to Grayscale" in Universal Access Preferences.

I think preference settings should not have keyboard shortcuts because of this very problem. Perhaps there should be a disable checkbox for this feature?

Wow! This was very helpful. I had the same problem today (years later) and the normal way of adjusting contrast did not help (F14, 15). But adjusting contrast with the keyboard shortcut option-command-control and then the "," or "." fixed the problem. Text is readable again, grays are back.

Thanks!
