G5 Stuck In Gray Scale Display Mode

Hi,

My son used control-option-command-8 to switch to gray scale, then again to get negative gray scale, then logged out. After logging back in, using control-option-command-8 again does not restore color, it just inverts the gray scale. Other accounts on the same system don't get stuck in gray scale.

I tried zapping the PRAM and it had no effect.

How do I get color back?

Thanks,

Alan
 
System Prefs/Universal Access and click the buttons. I've had the Function key options fail for a time.
