It was hard to tell in the original pictures I posted, but those are in fact two entirely different brick mixes. Here is a blowup that makes that a little more clear:
The bottom mix has a variety--some of the bricks are more greenish, others more pale, others a bit darker.
The top mix is all one color, all the same shade. And I don't think they match any of the bricks below--it is a slightly more purple red, to the more orange red below.
The mortar color might be different too, but in person, it is the two different brick mixes that really stand out (in a horrible way).
By the way, you can download higher quality versions of those photos from the links above and pick out a lot more awfulness. Warning--you might not want to eat right before you do that.
