Everyone has a different subjective experience of everything because our neurology is different. No person has the exact same arrangement of rods and cones in their eyes, or cilia in ears, or anything like that. No two people have the same arrangement of neurons or dendritic connections in their brain. No two people have the same weights to each of their neurons, so to speak from a ML standpoint. And because of that, all of our experiences are unique and subjective. BUT, we are SO similar genetically that there is SHARED properties to nearly all experiences among ALL humans, strongly arguing for objectivity to it. Why is red specifically what we perceive as red is not answerable. How it affects you cognitively and emotionally is based on the entirety of your upbringing and past experiences as well as your sense neurology. Our brain has quite a lot of neurons and connections! Trillions of connections and billions of neurons! A lot can change and be affected in innumerably complex ways! It's more than sufficient to explain the entirety of our subjective experience.
