#maybe please?

So if anyone out there is experienced with phenotyping budgies I need some help figuring out what my little yellow lady is. Her eyes are v dark. She has a tiny blue patch on her back just above her tail feathers as well that she won’t let me get a picture of. She is pale yellow- whitey greyish in some places. Can’t decide if she’s a Lutino or df spangle or something else (that blue/green butt spot has me tripping)
