Back to Digby's complaint (post #3, above): I now realise that he was probably complaining about a problem with the colour printing of the rainbow as it is supposed to be seen by tritanopes, but probably printed for the benefit of standard trichromats, who see blue. It probably had too much blue in the "green" region, which Digby would therefore have seen as dark, and not representative of his rainbow.
