I have a boy named Shadow, he was a light grey when he was young but now his yellow has washed down over his body, and I'm not to sure on his wing color. His mum was a gf opaline, normal dark wings apart from the opaline bit, very blue torquise color and dad an albino.
From the pictures I'd say your Shadow is a Golden face. The yellow is very rich in colour to be yellow face type II. The fact that the mother is golden face further proves the passing of that trait to Shadow. I think he is a mauve single factor golden face full body colour greaywing budgie.
I'm moving this thread to the Mutations and Genetics section where it's most appropriate and due attention will be given.
When you have questions on colour mutations, it's best to post in that specific section of the forums.
RIP sweet Tito (Summer 2008 - January 17th 2013).
You are missed and never will be forgotten.
