It is proven that any hidden variable theory of the type proposed by Meyer [Phys. Rev. Lett. 83, 3751 (1999)], Kent [ibid. 83, 3755 (1999)], and Clifton and Kent [Proc. R. Soc. London, Ser. A 456, 2101 (2000)] leads to experimentally testable predictions that are in contradiction with those of quantum mechanics. Therefore, it is argued that the existence of dense Kochen-Specker-colorable sets must not be interpreted as a nullification of the physical impact of the Kochen-Specker theorem once the finite precision of real measurements is taken into account.
