They once existed, but they are certainly not an average find anymore, especially with today's outbreak of the ambullies (which are bred specifically for the color blue typically or size). You have the entire concept of "blue pits" being madly driven by BYB's, that lead many people to believe that, they are pit bulls solely on that (like the red nose craze) or, if their dog is not overly done like an ambully, it is therefore, a pit bull.
It's honestly very complicated to simply explain blue and pit bulls to the average individual because blue bullies have exploded in popularity (another great opportunity for BYB's), that they range in so many different variants, that confuse the general public even further. When people already have such a hard time spotting an actual pit bull on top of it all. Every person that has tried to pass of their dog as a, " full blooded blue pit", automatically screams NOT pit bull.
