I can’t speak for the other 4 people, but I was taught to perform that trick in kindergarten. They even asked me which color was my favorite. Later, in high school, I learned about the difference between red and blue on the electromagnetic spectrum. And still later, in college, I learned about color perception in Psych and CompSci classes. For a while, I imagined that everyone had learned the same color facts that I had.
Then I ventured into a philosophy classroom, was exposed to G.E. Moore talking about “yellow” and “qualia”, and I came to understand that not everyone had the same educational advantages I had.
The philophical question of qualia has nothing to do with how the sensation of color gets to your brain. It’s about what it does in your brain that makes you conscious of it.
