Hi all,
As an aside, there are some interesting notes on this and related problems of colour descriptions in the Remarks on Colour by Ludwig Wittgenstein.
These Remarks signal the moment of fracture between Wittgenstein’s thinking in the Tractatus and his later work in the Philosophical Investigations.
Terry, it often seems to me that you tend to think in the logical positivist manner, which drew inspiration from Wittgenstein’s Tractatus. Others on this list take their inspiration in part from Wittgenstein’s later work of the Philosophical Investigations.
A useful book that gives a detailed gloss on Wittgenstein’s struggles with colour, which so radically changed his thinking, can be found in:
