When it comes to the opposite of being "art crazy over," there are a few antonyms to consider. Firstly, someone who is disinterested in art might be described as apathetic or indifferent towards it. Secondly, a person who dislikes or even hates art could be referred to as art-averse or art-phobic. Finally, someone who has no interest or appreciation for the value of art might be called art-ignorant or art-unaware. Regardless of which antonym best fits, it's important to keep in mind that art is a subjective and personal experience, and everyone's relationship with it is unique.
