I mean… Your brain is just making shit up.

Color? It’s the brain interpreting the visible wavelengths of light. Maybe what you see for red isn’t the same as anyone else. Maybe the difference between high and low pitched sounds, sound different to each individual because the experience of hearing a sound is, again, just the brain’s interpretation of data.

The data can be the same for everyone, and the experience can be totally different because the brain interprets that data differently for each person. It certainly would explain why some people like subjective things and others do not; such as colors, music, flavors, etc.
