What is the color of the camera lens on the black iPhone 4 with FCC ID ending in A?

I have a black iPhone 4 with FCC ID ending in B. I recently broke the glass on the back of my iPhone and ordered a replacement on eBay. The FCC ID of the replacement glass ended in A. I also noticed that the color of the camera lens is clear; however, the color of the lens on my cracked glass has a bluish tinge. Please verify the color on the camera lens on the back of an original back glass for the iPhone 4 with the FCC ID ending in A. Thanks!
