Summary
In “The Psychophysics of Color” (Color Categories in Thought and Language, 1997), Jameson, K. and Roy G. D’Andrade argued that Hering’s theory which contains opponent processes of color is not completely true and do not fit for many color spaces. Also, the authors discussed about Berlin and Kay’s perceptual fundamentals, “basic colors segregate well not because they are universally named but because they are well separated in color space” (Berlin and Kay, 1990: 1985, pp313). The authors explained that there are three-dimensional spaces in color; cardinal axes of space such as light and dark, LGN named form lateral geniculate nucleus that contains basis of purity and uniqueness of colors, and history of color development. Therefore, in this chapter, Aoki pointed out that there are three similarities of color scaling such as Thurtonian scaling, ratio judgments and interval judgments. However, he also mentioned that there are some differences in oriental colors because they have different views of opposite colors in terms of relationship, appearance and visual. To sum up, in this chapter, Jameson, K. and Roy G. D’Andrade stated that opponent colors are not able to be said the same all the time because they have many differences depend on theories.
Critique
This chapter’s title “It’s not really red, green, yellow, blue: an inquiry into perceptual color space” was very good in the content because I understood that we can say “red” or ”blue” in one word, but they have many differences by how we recognize them. There were some people, who argued opponent colors by having their theories with explanations, so the evidences were quite clear. The chapter was divided into some sub-topics, however, the connection between them does not have unity. In addition, sometimes sentences did not have any definition of abbreviation. Although, there were some charts to make the ideas easier to understand, they made me confused to understand all the better because they explained only about nanometer in scientific way.
