Someone else out there would know for sure since I'm not a vinyl buff; but doesn't the needle move up and down in the grove for one channel of sound and then left and right (back and forth) in the groove for the other channel? The needle follows the groove and moves in accordance--I don't see how color would effect that. Its possible that the durability of the vinyl isn't the same with different colors so that after 20 plays one vinyl might wear out quicker, but that's just hypothesizing.
