Writing color means facing language’s limits right away. Say red and the word already lies—it swallows vermilion, carmine, dried blood on cracked cement, a poppy petal pinned to a fascist’s lapel. The pull toward metaphor is almost gravitational. A sky stops being blue and becomes the color of longing. A dress isn’t yellow; it’s the hue of hope. Seductive, yes, and also a kind of descriptive cowardice. When metaphor replaces close looking, it dissolves the thing’s material reality. It tames color, turning it into a servant of human emotion instead of a physical fact with its own political and sensory weight. I want to propose a different discipline: writing about color as a grammar of light—a material event that happens between surface, eye, and the history that stains both.
The Physics of a Surface
Start not with the color’s name but with the conditions under which it appears. What’s the surface? Matte or gloss? A matte surface scatters light, trapping color inside its microscopic roughness and giving it a dense, unyielding presence. A gloss surface throws a percentage of the light source straight back at you, creating a spectral highlight that’s the color of the bulb, not the object. Writing this means accepting that color isn’t a stable property. It’s an event. The green of a Russian army uniform is one green at noon, another at dusk, and another still when it’s wet from rain or stiff with dried sweat. Describe the light’s angle and the fabric’s texture, not the soldier’s mood. The mood will arrive on its own, through the precision.
Take a white wall. It’s almost never white. In a room with a north-facing window, it drinks the cool, indirect sky and turns a dilute blue-gray—a color without a common name but as specific as a fingerprint. Under a single incandescent bulb, that same wall becomes weak tea, a yellow-brown that climbs the plaster and deepens in the corners where the light dies into shadow. Writing white just erases the whole drama. Instead, write the light. Write the source: the color temperature in Kelvin, if you know it, or the filament’s quality, or the time of day. Write the shadows: sharp, from a point source, or soft, from an overcast sky? Color lives in the interaction, not in the idea.
The Pigment’s Genealogy
Every manufactured color carries a history, and that history is often one of violence, extraction, or industrial synthesis. Ignoring this treats color as a purely aesthetic phenomenon—a political act in itself. When you write about a particular red in a Renaissance painting, you’re writing about the cochineal insect, crushed by Indigenous hands in Oaxaca under Spanish colonial rule, its body yielding a carminic acid so potent it became New Spain’s third most valuable export, after gold and silver. The red isn’t just red. It’s a concentration of labor, death, and global trade routes. You don’t need metaphor here. You can state the fact: the red is made of Dactylopius coccus, females only, 70,000 insects to a pound of dye. The color is a number and a species name before it’s an emotion.
Similarly, the Prussian blue of a cyanotype traces back to an alchemical accident in a Berlin laboratory in 1704. A pigment maker named Diesbach tried to create a red lake from cochineal, iron sulfate, and potash contaminated with animal blood. The result was the first modern synthetic pigment. It’s the blue of the sky, now, in our minds, because it was cheap enough to spread everywhere. But it’s also the blue of the cyanometer, an instrument invented by Horace-Bénédict de Saussure to measure the sky’s blueness—a circle of 53 shades numbered from white to black-blue. That’s a way of writing color: as a measurement, a tool, a lab mistake that became a standard.
The Eye’s Complicity
Color doesn’t exist without a perceiver, and the perceiver isn’t a neutral camera. The human eye has three cone types, sensitive to short, medium, and long wavelengths—roughly blue, green, and red. But that’s a gross simplification. The L cone’s peak sensitivity actually sits in the yellow-green, not red, and the S cone is so sparse in the fovea that our sharpest vision is effectively blue-blind. Writing color from the eye’s perspective means writing a biological filter. A small yellow patch against a large blue field seems to vibrate because the eye’s lens has chromatic aberration: it focuses blue and yellow at different planes on the retina. The vibration isn’t a metaphor for energy; it’s a failure of the lens to bring all wavelengths to a common focus. Describe the physiological effect, and the reader’s own body does the work.
Then there’s the history the eye carries. A color reads as beautiful or ugly, sacred or profane, depending entirely on cultural training. The ancient Greeks had no word for blue; the sea in Homer is wine-dark, a description that has puzzled scholars for centuries. The most plausible explanation isn’t that Greek physiology differed but that their color vocabulary was organized around luminosity, not hue. A dark sea and a dark wine share a quality of depth, of light absorption. When you write a color, you’re always writing inside a linguistic system that has already decided what’s worth naming. Resisting metaphor also means resisting inherited categories. Call the sea the color of wet slate or the color of a bruise on olive skin—not to be poetic, but to be exact.
Color as a Social Code
Fashion is a particularly fertile ground for color writing without metaphor because garments already function as a system of signs. A particular shade of pink in a garment isn’t just pink. It’s a Pantone number, a dye lot, a decision about who is meant to wear it and in what context. The pink of a “nude” bandage dress from a luxury house is, historically, the pink of a narrow range of white skin tones—a structural fact, not a metaphorical one. Writing this means naming the exclusion. Color is the evidence. You can describe the dress as a beige-pink that matches the inner forearm of a light-skinned person, a color that disappears on the body of anyone darker than a paper bag. That’s not a metaphor for racism; it’s a direct description of a material object that enacts racism through its wavelength distribution.
Similarly, the bright, almost synthetic greens and oranges of safety vests are colors designed by committees, specified in ANSI standards, measured in chromaticity coordinates. They scream see me not because of any inherent property but because they’re maximally distinct from the greens and browns of a construction site and the reds and yellows of traffic signals. Color is a function. Write the function. Write the contrast ratio against asphalt. Write the way the vest fades after six months in the sun, the fluorescent dye molecules breaking down, the color becoming a tired, dusty version of itself that no longer quite meets the safety standard. The fading is a record of time and labor, not a metaphor for decay.
The Discipline of the Adjective
Most color writing fails at the adjective. We reach for the atmospheric, the emotionally grand, and lose the thing itself. The fix isn’t to ditch adjectives but to make them work harder. An adjective has to earn its place by adding information not already implicit in the color name. Pale blue is redundant if you’ve already said the blue of a winter sky at 9 a.m. But the blue of oxidized copper sulfate crystals, a brittle, salt-crusted blue—here the adjectives specify texture and chemical process. They’re not decoration; they’re documentation.
One useful exercise: write a color as a recipe. If you had to mix this color from a set of base pigments, what would you use? For the color of a certain shadow on snow: ultramarine, a touch of raw umber, a lot of white, but the white isn’t enough to make it pastel; it’s still a dark color, just a dark color that is also white. This forces you to think in material composition, not emotional resonance. Another exercise: describe the same color under three different light sources—daylight, fluorescent, incandescent. The color shifts, and that shift is its biography. The object is a chameleon, not because it’s mysterious but because its surface chemistry interacts with different spectral power distributions. Write the chemistry. The mystery will survive the explanation, if the explanation is honest.
Politics in the Palette
Refusing to separate aesthetics from politics means recognizing that every color choice in a public space is a choice about who feels welcome. The gray of a government building isn’t a neutral gray. It’s a specific gray chosen by an architect trained in a tradition that equates gray with seriousness, authority, a kind of masculine rationality that excludes the decorative, the colorful, the allegedly feminine. Writing this gray without metaphor means naming the tradition: Brutalism, the International Style, Le Corbusier’s legacy. It means noting that the gray isn’t one gray but a range of grays, the color of poured concrete, which varies with the aggregate, the cement type, the formwork. The building is gray because concrete is gray, and concrete is gray because of the iron content in the limestone and clay from which the cement is made. The grayness is a geological fact before it’s an ideological one, but the decision to leave the concrete exposed rather than painting or cladding it is a political decision. Write the geology. Write the decision.
Color also operates in the language of protest and resistance. The purple of a feminist banner isn’t arbitrary. It’s the suffragettes’ color, chosen by Emmeline Pethick-Lawrence in 1908: purple for loyalty and dignity, white for purity, green for hope. But those are still metaphors. The material fact is that purple dye was historically expensive, associated with royalty precisely because it was rare; the suffragettes were reappropriating a color of power. The purple of a modern protest banner is likely a synthetic aniline dye, cheap and reproducible, a direct descendant of William Henry Perkin’s accidental mauveine from 1856. The color is simultaneously a symbol and a molecule. Writing only the symbol misses the molecule that made the symbol possible.
The Inadequacy of Language, Embraced
There’s a point where language fails, and that failure is itself a kind of information. The blue of a YInMn pigment, discovered accidentally at Oregon State University in 2009, is a blue that many people report as being unlike any other blue they’ve seen. It absorbs red and green light almost completely, reflecting only blue wavelengths in a very narrow band. The eye receives a signal that’s pure in a way few natural colors are. Writing this blue means writing the gap between the signal and the word. You can specify the wavelength, the reflectance curve, the chemical formula (YIn1-xMnxO3), and still, standing in front of it, the color exceeds the data. This isn’t a mystical excess; it’s simply the difference between a measured physical quantity and the lived experience of a human visual system that evolved in a world full of broad, messy spectra. Refusing metaphor isn’t refusing wonder. It’s locating wonder in the precise, in the gap between what we can measure and what we can say.
Writing color without metaphor is a practice of attention. A commitment to the object, the light, the body, and the history baked into every pigment and surface. It’s a way of saying: this thing is itself, and its meaning isn’t something I impose but something I uncover by looking harder. The more precisely you describe the color, the less you need to tell the reader what to feel. Feeling comes from rigor, from the trust that the world is interesting enough without our editorializing. The red isn’t rage; it’s the color of the light that remains after the green is subtracted by a leaf in autumn. The rage is in the subtraction, and the subtraction is a fact.
Frequently Asked Questions
Why avoid metaphor when writing about color? Isn’t metaphor the whole point of descriptive writing?
Metaphor often works as a shortcut that skips sensory precision. Call a wall the color of loneliness, and you’ve told the reader nothing about the actual wavelength of light reflecting from the plaster. You’ve swapped an emotional placeholder for a physical description—a disservice to both the wall and the reader. Exact description—color temperature, texture, the way light falls off at the edges—grounds the writing in a shared material reality. Metaphor can still have a place, but it should be built on a foundation of close observation, not used as a replacement for it.
How can I describe a color accurately if I don’t know the technical terms like color temperature or pigment names?
You don’t need a chemistry or physics degree. Start with what you can observe: the light source (sun, lamp, candle), the surface quality (glossy, matte, textured), and comparisons to common materials. The color of a brown eggshell, but darker and with a greenish undertone, as if the egg had been dipped in olive oil—that’s a description relying on shared reference points, not jargon. The key is being specific about the components you can name. Over time, you can pick up technical vocabulary if it serves your writing, but the discipline of looking closely is available to anyone.
Does writing color without metaphor make the prose too dry or clinical?
Only if you believe facts are inherently dull. A pigment’s chemical composition, a dye’s colonial history, the retinal mechanics of color perception—these are rich, often violent, deeply human stories. A precise color description can be more emotionally affecting than a vague metaphor because it invites the reader to inhabit the same sensory space. Dryness is a risk if you stop at the data, but data is never the endpoint. It’s the structure on which human meaning is built. The challenge is to write the data with enough clarity and attention that the meaning becomes undeniable without being stated.
Can this approach apply to digital colors on screens, which have no physical surface?
Yes, but the material context shifts. A digital color is a set of RGB values, a hex code, a specific emission of light from a screen made of liquid crystals or organic LEDs. To write a digital blue without metaphor, you can specify the hex code (#0000FF for pure blue), the sRGB coordinates, or the fact that this blue is an additive color, created by emitting light rather than subtracting it from a white surface. You can also describe the screen: its brightness, color calibration, the way the blue shifts when you tilt a laptop display. The color is still a physical event—photons hitting your retina—even if the surface is glass and the pigment is a semiconductor. The same discipline of precise observation applies.
