Df Violet Olive Green?

[Budgielover13 0]

okay I have a male olive green budgie who is about 18months (got him from a colony breeder as a baby).  Before he's first moult he had quite a purplish tinge near his vent region, and still has a slight purplish tinge.  I am hoping to breed with him and I was wondering if he would be a double factor violet and if I breed him with a visual violet hen, would they produce violets? Thanks for any information anyone can supply!
