Pictures would help. Could be dirty feathers, or could be from genetics.

My guess is that this is genetic color leakage from his breeding. The reddish on his wing shoulders particularly.

Genetic color leakage is not uncommon. Since this breed is already a cross breed, it's not shocking. Even birds that are considered "pure bred' can have color leakage if there is a genetic marker from something in the blood line. Some things are recessive and only show up sometimes. It only matters if you are breeding for a standard and want to maintain the standard. Otherwise, it's less important.

I've no personal experience with that particular breed. From what I read after several generations the feather quality decreases and you have to breed them back to black to fix that. I am NOT good at predicting genetic outcomes in cross breeding, it makes my head spin. From what I've read the blue gene does not breed true, and the lavendar gene comes with feather issues. I would do some research and reading to find out what kind of breeding will give you the results you are after.
