Names for colors vary widely across languages, but color categories are remarkably consistent [1–5]. Shared mechanisms of color perception help explain consistent partitions of visible light into discrete color vocabularies [6–10]. But the mappings from colors to words are not identical across languages, which may reflect communicative needs – how often speakers must refer to objects of different color [11]. Here we quantify the communicative needs of colors in 130 different languages, using a novel inference algorithm. Some regions of color space exhibit 30-fold greater demand for communication than other regions. The regions of greatest demand correlate with the colors of salient objects, including ripe fruits in primate diets. Using the mathematics of compression we predict and empirically test how languages map colors to words, accounting for communicative needs. We also document extensive cultural variation in communicative demands on different regions of color space, which is partly explained by differences in geographic location and local biogeography. This account reconciles opposing theories for universal patterns in color vocabularies, while opening new directions to study cross-cultural variation in the need to communicate different colors.

are color categories the evolutionary product of their usefulness in communication, or is this an accidental benefit they give us? it is argued here that embodiment constraints on color categorization suggest that communication is an add-on at best. thus, the steels & belpaeme (s&b) model may be important in explaining coordination, but only at the margin. furthermore, the concentration on discrimination is questionable: coclassification is at least as important.

steels & belpaeme (s&b) ask how autonomous agents can derive perceptually grounded categories for successful communication, using color categorization as an example. their comparison of nativism, empiricism, and culturalism, although interesting, does not include key biological and technological constraints for seeing color or learning color categories in realistic environments. other neural models have successfully included these constraints.

Color has been scientifically investigated by linking color appearance to colorimetric measurements of the light that enters the eye. However, the main purpose of color perception is not to determine the properties of incident light, but to aid the visual perception of objects and materials in our environment. We review the state of the art on object colors, color constancy, and color categories to gain insight into the functional aspects of color perception. The common ground between these areas of research is that color appearance is tightly linked to the identification of objects and materials and the communication across observers. In conclusion, we argue that research should focus on how color processing is adapted to the surface properties of objects in the natural environment in order to bridge the gap between the known early stages of color perception and the subjective appearance of color.

Our experience of color results from a complex interplay of our perceptualand linguistic systems. At the lowest level of perception, our visualsystem transforms the visible light portion of the electromagnetic spectruminto a rich 3D experience of color. Despite our ability to discriminatemillions of different color shades, most languages categorize color intodiscrete color categories. Perception provides constraints on the likelylocations of color word boundaries but does not fully define color wordmeanings. Once acquired, although language likely does not influence thelowest levels of color perception, language does influence our memory andprocessing speed of color. One approach to examining the relationshipbetween perception and language in forming our experience of color is tostudy children as they acquire color language. Children produce color wordsin speech for many months to years before acquiring adult-like meanings forcolor words. Research in this area has focused on whether children’sdifficulties stem from 1) an inability to identify color properties as alikely candidate for words meanings or alternatively 2) inductive learningof language specific color word boundaries. Supporting the first account,there is evidence that children more readily attend to object traits likeshape rather than color as likely candidates for word meanings; however,children seem to have successfully identified color a candidate for wordmeaning before they begin to produce color words in speech. There is alsoevidence that pre-linguistic infants, like adults, perceive colorcategorically. While these perceptual categories likely constrain themeanings that children consider, they cannot fully define color wordmeanings because languages vary in both the number of location of colorword boundaries. Recent evidence suggests that the delay in color wordacquisition primarily stems from an inductive process of refining theseboundaries.

Color is a continuous variable, and humans can distinguish more than a million colors, yet world color lexicons contain no more than a dozen basic color terms. It has been understood for 160 years that the number of color terms in a lexicon varies greatly across languages, yet the lexical color categories defined by these terms are similar worldwide. Starting with the seminal study by Berlin and Kay, this review considers how and why this is so. Evidence from psychological, linguistic, and computational studies has advanced our understanding of how color categories came into being, how they contribute to our shared understanding of color, and how the resultant categories influence color perception and cognition. A key insight from the last 50 years of research is how human perception and the need for communication within a society worked together to create color lexicons that are somewhat diverse, yet show striking regularities worldwide.
