Well respectfully okie when you mentioned Mr. Knierem and Mr. Carnathan that explains it and even moreso if your "reverse" colored dogs are from Howards line of dogs. I like Mr Howard and always enjoyed him but as all breeds and line not everyone will know what built them....but was not Howard foundation dog Carnathans Bruno? ......
I never had tthe chance to ask Mr. Howards about this before his stroke...but you figure it out.
See pic on the right of Bruno advertised as a registered "catahoula bulldog"
