Most of them I've seen look pretty similar in coloration. But I must admit I wasn't looking too close, since I wasn't looking for one at back then.
I took a short video and here's a screen shot from it. Here they are, the area where the blue meets the yellow on top was the pale spot I was referring to. Maybe this is normal, since this may be the only time I've seen them from the top.
