I also see that Jonathan Cohen’s nice colour manifesto is in press at _Philosophical Review_. I think the criticism I (rather clumsily) make “here”:http://tar.weatherson.org/archives/000662.html and “here”:http://tar.weatherson.org/archives/000665.html against relationalism as a theory of colour talk still basically works, but relationalism as a theory of the metaphysics of colour seems very plausible to me for the reasons Cohen outlines. If I had a spare semester or two I’d write up something about why MacFarlane-style relativism is more plausible than the hidden variable theory Cohen endorses, but right now I don’t have that spare semester. And I can’t publish replies in the _Philosophical Review_, so I’m less motivated 😉
