How do color words such as “blue” “green” and “yellow” get meaning from their relationships to one another?

In the study of semantics, color words like “blue,” “green,” and “yellow” derive their meaning from their position within a specific lexical field rather than as independent, atomistic units.

According to the structuralist approach, the meaning of a word is a function of the relationships it maintains with other terms in its subsystem. While the boundaries of these colors may be imprecise, their relative positions are fixed: “green” is defined by its placement between “blue” and “yellow.” Consequently, knowing the meaning of “green” implies understanding both what can be described as green and what cannot, as well as recognizing boundary terms like “yellowish green” or “bluish green.”

Rather than labeling pre-existing natural categories, languages impose structure upon the psychophysical continuum of color. By assigning specific words to areas within this continuum, a language creates its own unique semantic structure, which speakers learn as they acquire their culture.1
