Yes, thank you. Section 7.2 describes the perceptual correlates of colour,
hue, colourfulness and brightness. Hunt finishes the first paragraph of this
section with the following, in brackets: "In the past luminosity was
sometimes used for this attribute instead of brightness". So, it clear, by
Hunt's account that "Luminosity" is different from "Visibility". I don't
want to belabor this point in vain but your point is well taken.
