Here's an article from Consumer Reports in which they claim to debunk the rumors of Kinect having problems because of skin tone.

November 4, 2010 Consumer Reports debunks the 'racist' Kinect
Video: Consumer Reports
Shortly after the first Microsoft Kinect for Xbox reviews starting appearing in the wee hours last night, another Kinect story cropped up. It seems some testers encountered difficulty in getting the Kinect to identify players with darker skin color.
According to GameSpot:
[Our] testing suggests facial recognition features of Microsoft's motion-sensing camera system might not work properly for some gamers... In testing the Kinect, two dark-skinned GameSpot employees had problems getting the system's facial recognition features to work."Consumer Reports did not encounter this issue with the Kinect and facial recognition when we first tested it. But it did remind of us a similar rumor about a "racist" HP laptop—which we debunked—last year. So we decided to test again the Microsoft Kinect with two players of different skin tones, in varying light levels.
Here's what we found: The log-in problem is related to low-level lighting and not directly to players' skin color. Like the HP webcam, the Kinect camera needs enough light and contrast to determine features in a person's face before it can perform software recognition and log someone into the game console automatically.
Essentially, the Kinect recognized both players at light levels typically used in living rooms at night and failed to recognize both players when the lights were turned down lower. So far, we did not experience any instance where one player was recognized and the other wasn't under the same lighting conditions.
This problem didn't prevent anyone who was affected from playing Kinect games, since it can "see" and track players' bodies and motions using a built-in infrared lighting system.
Take a look at our video to see how we tested and hear the full results.
