Good points. The contrast is usually qualia-v-quanta. I think color can be communicated and we have an "RGB" language for doing so that makes it more quanta than qualia. So extending your point to Schrodinger, if you're a wine connoisseur you have a language for communicating the taste of wine. Most of us don't speak it, but most people don't speak differential equations either. But those are all things that can be shared. The pain of a headache generally can't be perceived by two different people. But there are experiments that use small electric shocks to try to produce objective scales of pain. So I think you are right that it is a matter of having developed the language; I just don't think color is the best example.

I disagree here. No qualia are communciable in the sense that quanta, or numbers, are communicable. We can talk and understand talk on color only because we bet that we share similar experience in front of electromagnetic wave with certain wave-length.

We only agree on numbers and counting because we distinguish objects in the same way. Otherwise your mother could not have taught you to count.
