its the same color. I thought the same thing at first, but if you put it in something like photoshop, and cut out tiles A and B, and then put them next to each other off to the side, you can see that its the same color, and hows that for one biga$$ sentence! For further proof, you can check the color make-up of each tile using the eye-dropper function. They're the same!
