Our relationship with colors seems universal. The sky is blue, grass is green, blood is red. Yet this apparent certainty begins to falter as soon as we take an interest in the world’s languages. Some cultures do not have specific words for colors that we consider fundamental. This reality, often misunderstood, raises an essential question: does the absence of a word mean the absence of perception? Recent research in linguistics and cognitive science shows that the answer is far more subtle and revealing about the way language shapes our vision of the world.

Language and color perception: a complex relationship

For a long time, color perception was thought to be strictly biological and therefore identical in all human beings. However, linguistic studies have shown that while visual capacity is universal, the way colors are categorized varies greatly from one language to another.

In some communities, there are no distinct words for blue and green, or even no abstract terms referring to color as an independent category. This does not mean that these populations cannot perceive these shades, but rather that they do not linguistically isolate them. Language acts here as an attentional filter: it highlights contrasts considered relevant for everyday life while leaving others in the background.

Recent studies show that perception remains intact, but that memory, rapid discrimination, and verbalization of colors are influenced by the available lexicon. Language does not limit vision; it structures the way we conceptualize it.

Why some languages have no words for colors

The absence of words for colors can be explained by several historical and environmental factors. Linguists have identified a nearly universal hierarchy in the emergence of chromatic terms. Languages generally begin by distinguishing light from dark, then red, before gradually introducing yellow, green, and finally blue.

The case of blue is particularly emblematic. This color is rare in nature in the form of stable pigments. In many traditional societies, the absence of blue pigments delayed the emergence of a specific term. The sky, for example, is often described by reference to its brightness or its state rather than by an abstract color.

Languages such as Pirahã in the Amazon, Mursi in Ethiopia, or Warlpiri in Australia illustrate this logic. They describe objects through their texture, their shine, or their function rather than through chromatic categories. Vocabulary thus reflects the cultural and ecological priorities of each people.

What field studies reveal about cognition

The research conducted in recent years among populations such as the Tsimane’ of the Amazon or the Himba of Namibia has profoundly renewed our understanding of human cognition. These studies show that the acquisition of color words is a long process, even in industrialized societies, and that the boundaries between categories vary according to languages.

Among the Tsimane’, for example, linguistic contact and bilingualism have led to the appearance of new color terms. This lexical transformation is accompanied by changes in categorization strategies, without altering visual perception itself.

These observations confirm that language influences cognition not by determining what we see, but by structuring the way we organize and memorize visual information. Linguistic diversity thus reveals different strategies of attention rather than perceptual deficits.

Linguistic diversity as a key to cultural understanding

Understanding why some cultures have no words for colors makes it possible to move beyond an ethnocentric view of language. Rather than seeing this as a lack or a delay, linguists now speak of adaptive strategies. Each language emphasizes the distinctions that are most useful for survival, communication, and cultural transmission.

This perspective is essential at a time when many languages are threatened with extinction. With them, unique ways of seeing and interpreting the world disappear. Studying color words therefore also means defending linguistic diversity as a cognitive heritage of humanity.

To explore this perspective further, it is possible to consult recent scientific syntheses on the relationship between language and perception, such as those published by the journal Nature Human Behaviour, which show how linguistic categories influence attention without altering sensory perception.

What languages without color words teach us

To better understand this phenomenon, here are some key lessons drawn from contemporary research:

  • The absence of a color word never implies an absence of visual capacity.

  • Chromatic categories emerge progressively according to cultural and material needs.

  • Blue is often the last color to be named because of the rarity of pigments.

  • Linguistic contact and bilingualism can rapidly transform the color lexicon.

  • Linguistic diversity reveals different ways of structuring attention and memory.

These findings invite us to rethink our relationship with language. Words are not simple labels placed on reality; they shape our cognitive habits and our perceptual priorities.

To extend this reflection, the Savoir en bref collection published by Five Minutes offers other accessible works devoted to the human and cognitive sciences, providing a clear overview of major contemporary questions.

The question of color words reminds us that our vision of the world is never neutral. It is shaped by history, environment, and the language we speak. Exploring these differences means learning to see differently and to recognize the richness of human cultures.
