I don't understand where this perceived confusion comes from (despite, or because, I read much of the relevant literature).

If we have an electronic device that emits light at 450THz and another that detects light and reports what "color" it is (red), then we can build/execute all of that without accounting for "redness" (except of course in the step where it decides what to call the "color"). Is there a problem here?

Is color a special topic here? Do we have the same issues in phenomenology of sound?

If we have an electronic device that outputs sound at 264.298 Hz and another that detects sound and reports the "musical note" (middle C) then we can build/execute all of that without reference to "middle C -ness". Is this a problem?

FYI: Unlike electronic devices, your visual system doesn't detect absolute color, hence these illusions.

Indeed. But one wouldn't want to suggest anything mysterious is responsible.
