Blue borns though have a much higher fatality rate as newborns, and if they do thrive at birth, they can go on to lose a lot of their hair, and have significant skin and health problems. It is rare because no one wants that to happen. If it were rare, but good, the reputable breeders on this board would be breeding blue borns all the ding-dong-day long.
Basically, its like two adults getting married that carried genetic markers for a very potentially fatal genetic disease, in the hopes that they would make babies that had the disease. Makes no sense. And just like when something like that accidentally happens, you hope and pray that the child thrives and does well, but most people would never go on to have more children once they know what will happen.

Perfect way of explaining!
