📄 What is the Colour of the Feeling (A Case Study of English Idioms with Colour Components)

Summary

The article asks why English idioms that name emotions so often contain a colour word. It argues that the contrast between warm and cold colours organises their meaning. This is a qualitative, descriptive study, not a corpus experiment. The authors take a few basic colour terms (red, blue, white, black, gray) and discuss idioms from phraseological sources such as Kunin's English-Russian phraseological dictionary and Brewer's Dictionary of Phrase and Fable. They describe idiomaticity from two sides. Reinterpretation looks at how an expression came about, and opacity looks at how a listener decodes it. Some idioms grew out of literal phrases, such as the bullfighting image of a red rag. Others never had a literal use, such as a blue moon. The central claim is that inside these idioms the colour word stops naming a hue and instead conveys an emotion's "temperature." Red signals hot anger and passion. Blue, white, black and gray signal sadness, fear, gloom or grief, often motivated by bodily reactions like flushing or paling. The authors concede that the reasoning is speculative. They see value for stylistic analysis and for teaching English as a foreign language.

Key points

• The material is a small set of basic colour terms. Most English words for shades carry no emotional meaning in idioms, while other languages may behave differently.
• Example idioms analysed include to see red (rage), like a red rag to a bull (irritation), to be in the blue (low mood), as white as a sheet/ghost (fear), black as night/sin (gloom, despair) and gray from grief.
• Idioms that are opaque and were never used literally are exemplified by once in a blue moon, blue blood, and the dilemma idiom that sets the devil against the deep blue ocean.
• The physiological motivation follows Vasilevich et al.: anger raises blood flow and body temperature, while fear drains blood and causes paleness and coldness. This maps onto warm and cold colours.
• The cultural motivation for blue = sadness is traced to the blues music of African-American slaves. The paper also cites the calming, depressing physiological effect attributed to blue.

Interesting ideas

• I1. Reinterpretation and opacity are treated as two views of one phenomenon: one from the producer's side, one from the hearer's side. This lets the same idiom be described differently for generation and for understanding.
• I2. Reinterpretation can hit a single component rather than the whole phrase. The colour word keeps its slot but swaps its meaning from hue to emotion, which gives a partially compositional reading.
• I3. Emotions are placed on a warm–cold axis tied to bodily signs such as flushing and paling. This gives a small, explainable feature linking physical description to inner state.
• I4. Idioms are split into those traceable to a once-literal collocation and those never used literally. This is a useful diagnostic for whether a literal reading should even be tried.
• I5. The paper notes that only a few basic colour terms carry emotional meaning, while shade words do not. This suggests keeping idiom lexicons narrow and high-precision rather than generalising over all colour vocabulary.

For Mova

How these ideas could serve Mova, our small open language model — its files, stages and tests:

• I1 (back): Generation could store each idiom with its production-side motivation, so the system can explain why it chose see red over a literal paraphrase.
• I2 (frames): Instead of treating such idioms as opaque blobs, prag could keep the UD structure and relabel only the colour lemma's sense, so went white yields an Experiencer-in-fear frame with intact roles.
• I3 (world): The ontology could hold links from colour terms to emotion "temperature" and polarity, so a text world can infer a character's state from turned red or pale as death.
• I4 (answer): When answering questions on tales, a flag marking phrases like blue moon as never-literal would stop the reader from inventing a literal blue moon in the story world.
• I5 (learn): Self-induced repair rules for figurative colour senses could be restricted to basic terms, with shade words used as a negative control to check that the rules do not overfire.
