In Sanskrit I know two words, kaala and krishna, that can both mean black, dark, or dark blue (there is no distinction). Krishna (the god/avatar) is usually depicted as having blue skin, though it is obviously more likely that he was simply dark-skinned, like a Dravidian, and it is probably the lack of differentiation in the words used for these colours that gives him the blue skin.
When I had to learn Hebrew, I was surprised that there are separate words for blue and light-blue. An Israeli will never call a “light blue” a “light blue” – it is always tchelet. And I have read that this is similar for Russians, Japanese and Greeks.
Why There was No Word for Blue in Ancient Greece and How Homer and Aristotle Perceived Colors
There was no word for “blue” in classical Greece. The closest descriptions of blue are glaucous and cyan, which express the contrast between light and dark. They do not, however, define the color itself.
I thought about this today when arguing with my wife about whether an object was blue or green. (It was actually a turquoise colour that she saw more as a shade of blue and I saw more as a shade of green).
A small percentage of women are thought to be tetrochromatic. They possess four types of colour cone cells rather than our usual three. Theoretically, a person or creature with true tetrochromatic vision is able to have much greater sensitivity to colours, though this depends on the range of colours perceived by the individual cones and the possession of four, rather than three, colour channels to process the information received.
It is much more likely that our ability to differentiate between colours depends upon language and culture.
Researchers have been fascinated by the Himba people in Africa and their unusual perception of colours.
The Himba and the hidden colors of the world/
The Himba have no word at all for the colour blue, but a whole range of words available to describe shades of green, and it seems that the result of not having a word for blue means that they find it difficult to differentiate it.
Experimental psychology research has demonstrated that this linguistic classification directly influences their visual perception. When asked to identify a slightly different shade within a series of green hues, they succeed more quickly than individuals from other cultures. Conversely, when faced with a single blue shade among greens, they struggle to distinguish it, whereas an outsider would immediately see an obvious difference.
Now I’m remembering how in Orwell’s 1984 the control of language was used to constrain the ability to think, or even the ability to experience the world.
Julia: ‘I’ve seen oranges. They’re a kind of round yellow fruit with a thick skin.’
The study of the Himba suggests the same, and the article above quotes Witgenstein: “The limits of my language mean the limits of my world.”
And, says the article:
However, this linguistic influence on perception is not unique to the Himba. Studies show that in some Asian languages, which do not distinguish blue from green, speakers perceive these colors as a single entity. On the other hand, Russian speakers, who have separate words for light blue and dark blue, differentiate these shades more rapidly.
Thus, language is more than just a communication tool, it shapes how we see the world.
For the Himba, colours have a much greater significance to their lives than use as a practical means to describe their environment. And it is worthwhile too to remember that colours hold different significance in different cultures. The articles I found mentioning this are those intended for practical issues like marketing, advertising and decorating. An obvious example given is that whereas white usually is associated with weddings in the west, it is associated with death and mourning in the east. In India, it’s the colour worn by widows.
Color Psychology Across Different Cultures: Unveiling Global Perceptions and Meanings
Color psychology rests on several core ideas:
Colors evoke emotional and physiological responses
Cultural context influences color associations
Personal experiences shape individual color preferences
Color combinations can amplify or alter effects
Finally, it seems that even the same person may experience colours and light differently according to the state of their mind. This was once demonstrated to me in a music concert by the musician Steven Halpern.
He showed a series of colour slides prior to his playing a piece of music he had composed called the Spectrum Suite. After the performance, he showed the same slides. Now the colours appeared richer and warmer. I particularly remember that what had looked like a lemon-yellow beforehand, now appeared to be a rich, warm and deep yellow.
This connection between hearing and seeing may imply that our perception cannot be neatly separated between the senses and that our perception of the world is affected by other factors. A “spiritual” or “mystical” experience is sometimes described in a way that transcends the narrow limits of one or another senses, as when in Exodus 20:15 it is stated that “All the people saw the voices” ( וכל העם ראים את הקולות)
In the sense that no visual perception is objective, but is influenced by linguistic, cultural or emotional factors, every experience is “spiritual” and perception is never an unalloyed experience of reality. It depends upon what we bring to it.
