Looks to me like a standard/regular.
They can turn more orange over time. My Taco is also a standard one and he's now quite orange, e.g. orange beard, bright orange stripe near the ear (really like drawn with a crayon), light orange on the back and so on. Also on the side where yours appear grey/bluish, mine is purple.
So I'd say: Yours looks very much like a standard, and standard dragons are just not "boring" colored ones but you see can have very much and beautiful coloration.
