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 grays having a reddish tone; with the new color temperature this is no longer the case.
It’s great that Google seems to be listening to users who found issues with the lower brightness levels affecting how the colors look and as such, tweaked the color temperature to make them look more accurate. But color gamut is a tricky thing and is always subjective. Many users may not like the new color temperature settings because they’re used to the way it looks. And although Google is trying to be proactive, the responses from users in the Google support forum indicate that more adjustments may be needed.
