Of course APBTs can be blue. They weren't at all unheard of in the gamedogs of the past. The thing is, however, the it's not a common dilution. And APBTs weren't bred for color. They were bred for gameness. For their performance.

The reason blue dogs are what they are is because the color was isolated. Breeders began to breed for the blue coat, paying no mind to the working aspects of the breed. It became a popular color to breed for in Amstaffs, and still is. Then, of course, you had people take those Amstaffs (and, in the very beginning, APBTs) and warp them, possibly mixing them with other breeds of dogs, though there's a lot of debate on that. Either way, they bred blue dog after blue dog after blue dog, selectively breeding for the traits known in American Bullies today.

So blue is no longer considered a color associated with the true APBT. But blue dogs have popped up from time to time in gamebred litters.
