Homo ebony born to two violets?

I was talking to a breeder about a kit she had last week and was curious about the genetics, and if anyone had heard of something like this before. I placed a deposit on a homo ebony v/c male. Now both of his parents were violet! His paternal grandfather was a dark violet wrap but that is the only ebony in his pedigree from grandparents onward. He and his brother are both homo ebonies!
