My own experience isn't any more convincing than yours because I don't know what properties are necessary for me to feel the way I feel. I also don't know if my feeling is in any way similar to yours or that of a fly on the wall. So if someone built a very complex machine that was able to communicate with me like a human, and if that machine claimed to feel something very specific at the sight of yellow, it would not feel right for me to say "no, you're not feeling anything like a human would feel" because I don't know how other humans feel. I have no way of comparing my own feelings with those of other humans or non humans.
