Looks like normal green to me too, although the term "normal green" sounds boring and doesn't do the justice to the looks. I love "normal green" mutation, I used to have one budgie just like your goose, he had the most laid back and sweet personality. Once they molt, they have a head full of those gorgeous yellow feathers, which go really well with the bright green body.
My Henry is a normal green too. Swore I would never get one because they are so "ordinary". Out of my flock of 6 though he is the sweetest and most friendly, I just adore him. Wouldn't trade him for the rarest colour out there!
