So, I'm just yet again wondering about the mutation of my budgie. This is because his body colour is not even and he has patches of other shades of blue within it - as he sheds his feathers I see that some of his feathers has two different shades. He has a pied patch, though, so he must be pied obviously. He doesn't look like the other pieds I see around here though because his entire body is a solid colour, except for the white above the tail.
Hmm, well he has maybe 1 white feather right above one leg, although it doesn't always appear - isn't that "just" a fluff feather? He has no white patch between the legs, on the belly or the bottom. If anything, just the patch above the tail and maybe a couple of feathers on the top of one leg.
Since his cheek patches are a darker blue/violet and not a silver/pale'ish blue I think he is mauve. In real life his tail also appear to be a very dark blue rather than completely black.
