Attached is a ColorSync profile for the new 20" iMac. It was created with an i1 Display 2 hardware calibrator. The target was medium white (6500K) at gamma 2.2. It should be suitable for most purposes. To use, unzip the attachment and place the resulting .icc file in /Library/ColorSync/Profiles. You should then have an "iMac-i1" entry on the Color tab of your Display preferences. NOTE: Because all displays are slightly different, this profile may not be completely accurate on your system. It should get rid of the washed-out look of the factory profile, but you might notice a slight color cast if your display is much different from mine.
