Sorry if this is an easily searched request, but I didn't know exactly how to search for it! My 15 month old daughter got her hands on our iMac, and somehow my screen colors are all screwed up. I'm not sure how to explain it (I know there is a word for it, but can't recall it right now), but anyway the pics all look like film negatives and the rest of it is just a mess! Kinda cool, actually, but I can't stand it for any lenght of time. Went to system preferences and tried to fix it under "appearance", and "desktop/screensaver" but couldn't find anything. Any help would be appreciated!
