Users who have upgraded their Nexus S and Nexus One handsets to Android 2.3.3 update have been reporting an issue where the phone's screen takes on a more yellow tint.
Google's Ry Guy explain that the new yellow tint is indeed meant to be there, with a claim that the original colour profile was incorrect.
With your new OTA complete, you may notice a slight difference in the way colors are displayed on your Nexus S. For Nexus S, we have adjusted the color temperature settings to more accurately reflect darker colors at all brightness levels. The Gingerbread UI being darker, we found that the colors were not as accurate when the device was being used at lower brightness levels. For example, some users reported that the initial color temperature was too high leading to some darker greys having a reddish tone; with the new color temperature this is no longer the case.
