Bizarre glitch killing lighter color tones in Snow Leopard - there's an easy fix
A few months ago, my Mac ran into a spot of trouble and suffered a kernel panic. Yes, Macs crash too, it does happen. After rebooting, I noticed that shades like #fafafa wouldn't display as anything other than flat white once I'd logged into the system. Now, I was lucky in realizing that it was only after login, because I have my login screen's background set to an image that uses lighter shades on white, but since I knew it was only a problem after logging in, I checked my color profiles. Every time I tried to change profiles, the screen would flash like it was changing to the new profile, then instantly revert back.
It turns out, for reasons unknown, the contrast slider in the "Seeing" section of Snow Leopard's Universal Access preferences had gone slightly to the right -- wiping out lighter shades like #fafafa. After resetting the slider, images with lighter shades were back to normal, and color profiles began loading again. So, not only had the slider killed my shades, but it also seems to stop color profiles from going into effect when it's not on the setting for "Normal."
Universal Access preferences are located in Snow Leopard's System Preferences, fourth row down, right-hand side.
I have no idea why the slider shifted, and until yesterday, I thought I was the only Mac user who ever experienced this. Then a friend complained that his fairly new MacBook had a kernel panic and lost lighter tones. I looked around, and found several threads on Mac forums full of people wondering why their color profiles keep reverting on them as soon as they activate. Hopefully the next major update will do away with this glitch, but just in case it doesn't, you know there's an easy fix!
