The breed standard for colour says:
Colour
Red, fawn, white, black or blue, or any one of these colours with white. Any shade of brindle or any shade of brindle with white. Black and tan or liver colour highly undesirable.
I would be concerned if the breeder doesn't know what the correct name for the colour is.
If your interested in showing I would want to know how well the parents have done a t shows too.
Have you googled their names? If you do you will come up with any championship show results they may have had.
There are many people breeding this breed and an awful lot have little resemblance to the breed as it should look or behave, and most are not health tested. Both parents should e tested or be from two clear parents for a neurological condition, be eye tested for PHPV and hereditary cataracts and also really ought to be hip scored (but few seem to do this). Also slipping patellas are not uncommon.
