to add to this, what we believe we “feel” about something is our association of a thought with the culmination of our previous memories, along with physically biological influences mixed in. The color red being processed by our brain causes excitement, so it’s used in food to increase appetite, in interior decorating to make a scene more romantic and intimate, used in road signs to signify danger; mix the physiological reaction of something with the personal memories associated with it, and you get your personally emotional reaction.

going further up the comment chain, art doesn’t exist in a bubble, it’s a product of the artist that’s a product of the zeitgeist they existed in. Any piece of art can be picked apart by someone educated enough by the source material and the historical period it was created in; they can dissect the combination of influences that gave birth to the content itself, along with the techniques used. Even if the techniques are “new”, it’s still iterative and a product of other existing methods - either from other artists, or from other fields of expertise.
