Variations in colour perception have featured prominently in recent attempts to argue against the view that colours are objective mind-independent properties of the perceptual environment. My aim in this paper is to defend the view that colours are mind-independent properties in response to worries arising from one type of empirically documented case of perceptual variation: variation in the perception of the «unique hues». §1 sets out the challenge raised by variation in the perception of the unique hues. I argue in (...) §2 that the empirical findings are less dramatic than they might initially appear, and in §3 that accounting for the inter-personal differences is consistent with the view that colours are mind-independent properties that normal subjects veridically perceive, at least roughly speaking.

In "How to Speak of the Colors", Mark Johnston’s claims that eliminativism would require us to jettison colour discourse. In this paper, I challenge Johnston’s claim. I argue that a particular version of eliminativism, i.e., prescriptive colour fictionalism, allows us to continue employing colour discourse as we have thus far in the absence of colours. In doing so, it employs statistical models in its base discourse to derive high-level statistical constructs that can be linked to the fiction via bridge principles.

In the framework of fuzzy logic a definition of vague object is proposed based on the notion of fuzzy equivalence. Indeed, while a crisp object is defined as a “concrete thing” together with an equivalence, I propose to define a vague object as a “concrete thing” together with a fuzzy equivalence.
