Okay, so I installed Snow Leopard on my parent's Mac mini and it has a Hanns.g display connected to it. In 10.5 Leopard, the colors looked normal (still not as good as an Apple monitor, but colors were close enough). Anyway, like I said, I upgraded to Snow Leopard and now the monitor's color is all out of whack. I tried re-calibrating it and everything. The weird thing is, I got the Finder to look okay, but all of the blue icons in the Dock (iTunes, iChat, Safari, QuickTime etc) look PURPLE! Also, the menu bar selections are the same purple color instead of that light blue. The other weird thing is... looking at the Finder icon in the Dock looks half purple and half light blue, but when I hit cmd-tab, it looks half blue and half light blue. The cmd-tab icon of the Finder looks like I'd expect it to look, but all the colors are completely destroyed in the Dock. Another thing is... scroll bars seem to look like normal blue too. One more thing... when I tried doing the manual calibration, it shows you how bright to make the monitor with the little graphic. The graphic looked so washed out that I couldn't make the monitor dark enough (on the darkest setting) to get even close to the picture that the calibration tool wants me to see. Is Snow Leopard only compatible with Apple monitors? I installed Snow Leopard on my Mac Pro (Apple Cinema Display) and all the colors are consistent. Note: The colors look the same regardless of 2.2 gamma or 1.8 gamma, so please don't bring that up. I want BLUE icons... not purple!
