Is there a dictionary definition of the term 'Disney colour'?

They certainly seem to have their own swatch book.

Stylistically, perhaps, this wanders into the territory of other cartoon makers like Hanna Barbera and Warner Bros. Is that lilac?

So, I don't mind if some things are whacky in the picture. The posts are thick at the bottom and thin at the top, but only partly through perspective as the change is abrupt. Stylistically the place is a pot pourri of scenes and styles so joiners are context appropriate.
