Are you experiencing a total blue screen or is the tint of the screen just blue?

I have the same problem. Both on my iMac and my mac mini. It started after the update to mountain lion. Hardware details below.
iMac: 21,5-inch, 2009, 3,33 GHz Intel Core 2 Duo, 8 GB 1067 MHz DDR3, ATI Radeon HD 4670 256 MB.
Mac Mini, 2011, 2,3 GHz Intel Core i5, 8 GB 1333 MHz DDR3, Intel HD-video 3000 512 MB.
PLEASE HELP!! This is very frustrating!

I've noticed this happens when you change video card. When moving from onboard video to the other. If you open a program that uses the other graphics card reestablish the original colors and the normal color returns.
It is also an error that occurs since the upgrade to Lion Mountain.
I hope it is resolved, does anyone else knows how to stop changing color?

I found a workaround from the user "Umputun" in this discussion: Blue tinted screen after mountain lion
Umputun's tip works, but only as long as you turn off "Automatic graphics switching" every time that you reboot. (Thanks Umputun for the tip!)
Basically, if you turn off "Automatic graphics switching" before you boot, the discrete graphics card will be correctly initialized on boot. Then you can turn "Automatic graphics switching" back on, and you won't have the problem until the next time you reboot. I've tested, and this workaround continues to work even after sleeping and awakening my computer.
It looks like an error with the gamma correction. For whatever reason, the integrated graphics card is always initialized with the correct gramma settings, but the discrete graphics card is only correctly initialized when "Automatic graphics switching" is turned off. I didn't have this problem when using Lion, so it's definitely an error with Mountain Lion. Hopefully 10.8.2 will fix this.

I had the same problem and used gfxCardStatus to 'fix' the problem - it was a temporary fix but did not require rebooting. Then the problem just 'disappeared' for me - I've no idea why.
BTW - I am on a late 2011 MBP: I've seen this problem reported both here and on the Adobe Photoshop users forum. gfxCardStatus seems to do the trick for some. I really can't pinpoint exactly what first caused the problem or why I know longer have the problem.

I'm currently using "gfxCardStatus" and I notice that the error is when it goes from the integrated discrete graphics card and vice versa. That did not happen when I used the Lion system. It seems to fix the error manually changing board is not the solution, rather, Apple should fix this error. I hope it will settle it tinted screens for a while.
Tnks in advance

Have the same problem. Mid 2010 MBPro. Last update of ML doesn't help me. gfxCardStatus dosn't help also. Apple, fix please this bug!
