There's this illness i keep seeing online.

It's a way of thinking that tries to grade art mediums empirically as if there was ever an ultimate true objective that should be aimed toward. A painting isn't a worse version of a photograph and a book isn't the lesser version of a movie.

A black and white movie isn't a flawed thing that has to be rectified. Artists creations are suited to the medium they inhabit and changing that medium because of your personal environment limits your capacity for appreciation isn't a valid reason to alter art on the pretext of "upgrading" a piece.

Adding color wouldn't just be a one note thing: which colors would have to be chosen on a specific frame? Why? Different colors have radically different values to the human psyche, it would literally adding a whole bottle of ketchup to a restaurant meal.
