COULD THE CAVE ARTISTS ACTUALLY SEE THEIR COLORS? – CONTINUED, PART 2:

 This one is just for fun, perhaps more for philosophers, please don’t take it too seriously – I do not.

Then the question became whether the lack of blue was actually based on a physical difference, or was perhaps a cultural or linguistic question.

“Anthropologists took up the challenge next. They were curious about how color was perceived by traditional cultures with limited or no contact to outsiders. In 1898, anthropologist and psychiatrist W.H. R. Rivers went to the Torres Straits Islands, located between New Guinea and Australia, where he investigated the islanders’ color perception. Rivers was astonished to hear the elders describe the sky as black, and a child describe the sky as being dark like dirty water. Rivers and other anthropologists concluded that early humans and members of isolated cultures were not color blind. They saw the same colors we see but linguistically don’t distinguish beyond hues of white, black, or red. This might be a simple enough explanation for Homer’s wine-dark sea, but it still raises the question: did ancient peoples perceive the color ‘blue’?” (Hall 2018) Remember, it is difficult to cognitively contemplate a phenomenon that you do not have a name or label for.

“Before the color blue became a common concept, perhaps humans saw it but simply didn’t recognize it as such. Even more fascinating—or perhaps disturbing—is the realization that the way we perceive the world around us may be something of an illusion, a trick played on us not by some external force but by our own minds, shadows cast against the back of Plato’s allegorical cave. We are oblivious to whatever realities exist outside of our perception. While we modern humans can differentiate between 1 million colors today, our perception is still largely limited to eleven color categories (in the English language: white, black, gray, red, yellow, green, blue, brown, pink, orange, purple). More humbling is the fact that we humans get by with just three types of photoreceptor cone cells (corresponding roughly to red, green, and blue sensitive detectors). Somewhere, silently scuttling beneath Homer’s wine-dark sea, the modest mantis shrimp boasts 16 different types of photoreceptor cone cells, viewing the world through a kaleidoscopic vision of unknowable colors, the likes of which we can only dream.” (Hall 2018) Once again, I enjoy Hall’s slightly sardonic comparison of our human color vision to that of the mantis shrimp.

In  2018, Fiona MacDonald reported on a field trial conducted in 2006 by Jules Davidoff, among the Himba people of Namibia. “But just because there was no word for blue, does that mean our ancestors couldn’t see it? There have been various studies conducted to try to work this out, but one of the most compelling was published in 2006 by Jules Davidoff, a psychologist from Goldsmiths University of London. Davidoff and his team worked with the Himba tribe from Namibia. In their language, there is no word for blue and no real distinction between green and blue. To test whether that meant they couldn’t actually see blue, he showed members of the tribe a circle with 11 green squares and one obviously blue square. But the Himba tribe struggled to tell Davidoff which of the squares was a different color to the others. Those who did hazard a guess at which square was different took a long time the get the right answer, and there were a lot of mistakes. But, interestingly, the Himba have lots more words for green than we do.” (MacDonald 2018) They could see the one square as different, but lacking the mental concept of a color ‘blue’ they had trouble seeing it as different enough to point out. This tends to confirm the statement that we cannot fully comprehend something until we have a name (or label) for it.

MacDonald also reported on a “study by MIT scientists in 2007 that showed that native Russian speakers, who don’t have one single word for blue, but instead have a word for light blue (goluboy) and dark blue (sinly), can discriminate between light and dark shades of blue much faster than English speakers.” (MacDonald 2018)

In 2022 Nikola Jones explained a reasonable hypothesis for the development of color terms throughout the history of a culture. “There are several big datasets out there looking at color categorization across cultures. And the consensus is that there are some commonalities. This implies that there might be some biological constraints on the way people learn to categorize color. But not every culture has the same number of categories. So, there’s also this suggestion that color categories are cultural, and cultures experience a kind of evolution in color terms. A language might initially make only two or three distinctions between colors, and then those categories build up in complexity over time.” (Jones 2022)

I have already written about the use of hachure on ceramics by the Ancestral Puebloans in the American southwest, and the theory that it represented the color blue to them (see my column of 7 June 2025). The origin of the idea that hachure, closely spaced, parallel thin lines, used to fill a space might be intended to symbolize the color blue was credited to J. J. Brody by Stephen Plog (2003). “One of the common design characteristics on black-on-white pottery from the eleventh and twelfth centuries in the northern American Southwest is the use of thin, parallel lines (hachure) to fill the interior of bands, triangles, This essay explores a proposal offered by Jerry Brody that hachure was a symbol for the color blue-is examined by exploring colors and color patterns used to decorate nonceramic material from the of northwestern New Mexico. His proposal is supported and the implications of this conclusion for future studies of this nature are discussed.” (Plog 2003:1) This, however, was not a suggestion that Ancestral Puebloans could not see the color blue, they had a name for the color, comprehended it, and designated it as the color of the direction West in many of these cultures. The assumption is, rather, that good blue pigments are much rarer than blacks or reds, especially blues that would stand up to the firing of a piece of pottery. There are, however, some remarkable examples of blue pictographs in the American west although considerably fewer than most other pigments. I should also point out that most indigenous peoples lend spiritual significance to various colors.

I also questioned whether or not hachure on rock art might have also symbolized blue, even if painted on with a different pigment. Of course, the rock art we study does actually, if rarely, have blue pigments based on natural clays and other materials.

Given all of this, the basic question remains ‘did the ancient painters of cave art such as can be found in Lascaux and Chauvet caves see the same range of colors as we do?” There is certainly very little blue found in Paleolithic cave painting, but I take that as a lack of convenient sources of blue pigment at that time, not a lack of visual acuity in color determination. Most of the readily available sources of blue for them would have been in plants in the indigo family which, if used in painting cave walls, might be fugitive, leaving us no evidence of blue in Europe’s painted caves.

I hope you have found this as interesting as I.
