Coral Color: Meaning, Hex Code & How to Mix It

What color is coral?

Full strength

Diluted

Pale wash

Graded wash

Hex	#FF7F50
RGB	255, 127, 80
CMYK	0, 50, 69, 0
Warm or cool	Warm. It carries orange rather than blue, and the added lightness only makes the warmth easier to see, which is why it sits so close to skin and sunset colors.
On the wheel	Coral sits between red and orange, pulled up in value until it turns pink at the pale end. It leans warmer than a true pink and lighter than a true red.

The story of coral

Coral spent two thousand years being sold as a gem, and it was never a gem at all.

What people were buying is Corallium rubrum, a colonial animal that grows a hard, branching skeleton on the floor of the Mediterranean, mostly between 10 and 300 meters down, with outposts near Gibraltar, Cape Verde, and southern Portugal. That skeleton runs from pale pink to a deep, saturated red, and it takes a glassy polish that has nothing plant-like about it once it is cut and buffed. People have been pulling it up, carving it, and stringing it into jewelry since prehistory: coral turns up in ancient Egyptian burials and in graves scattered across prehistoric Europe, worn by people who almost certainly never saw the seabed it grew on.

Nodder, 1 November 1793. Platemark 10.5 x 6.5 cm. This is the object itself, the animal the whole color is named after, years before anyone tried to match it in a paint box.

Rome gave the stone a second job beyond decoration. Romans believed a branch of coral hung around a child's neck would keep danger away, a belief that survived the empire, ran through the Middle Ages, and was still current in parts of Italy as protection against the evil eye well into the 20th century. Children in coral necklaces turn up often enough in portraits from later centuries that the custom clearly traveled with the stone, long after nobody could say exactly why it was supposed to work.

Watercolor on ivory, framed 9 x 7.3 cm. The child wears a strand of coral-pink beads. The museum does not say what they are made of, but this is exactly how the old habit looks in portraits: coral worn young, for luck rather than decoration. The Cleveland Museum of Art, CC0.

By the 1700s the trade had a capital. Torre del Greco, on the slopes of Vesuvius outside Naples, got its own Royal Society of Coral in 1790, and the opening of the city's first coral factory in 1805 kicked off what locals still call the golden age of coral manufacturing, complete with a dedicated craft school by 1878 and a museum by 1933. Naples, Rome, and Genoa did the selling; Torre del Greco did the carving.

None of that history left behind a pigment. Coral was mined and carved, never ground and bound into paint, so there has never been a tube that matches the stone by chemistry rather than by eye. What painters use now is a warm red pushed toward orange and let down with water: a pyrrole orange on its own, or a scarlet warmed further and lightened with rose.

I like that the name outlasted losing its object almost entirely. Most people who ask for a coral pink have never held a piece of the actual stone, and would likely be surprised by how deep and how variable its real color runs. The paint kept the idea. The jewelry mostly stayed behind glass.

Pigment facts

Colour Index	Not a pigment. A color name; in watercolor it is mixed from a warm red and an orange, commonly a pyrrole orange used alone, or a scarlet warmed further and lightened with rose and plenty of water.
Transparency	Depends on the pigment. Pyrrole orange runs semi-transparent to semi-opaque. A scarlet lightened with rose stays close to transparent, since neither ingredient is naturally opaque.
Lightfastness	Excellent in modern versions. Pyrrole and modern rose pigments are rated for permanence, so a coral mixed today holds its color far better than the dyed cloth the name is sometimes confused with.
Granulation	Little to none. Both routes are fine synthetic pigments that dry smooth rather than textured.
Staining	Moderate to high, depending on the reds involved. Pyrrole pigments bite into the paper; a rose-based mix lifts a little more easily while still damp.
Toxicity	Non-toxic. The pyrrole and rose pigments used to mix coral today carry no heavy metals, unlike some of the older reds a painter might once have reached for instead.

These describe the pigment in general. Every brand's tube behaves a little differently, so test yours on scrap paper.

How to mix coral

Coral is easy to reach because it is just a warm red pushed toward orange and then let down with water or white. A pyrrole orange gets you there in one pigment. Without one, warm a red toward orange yourself: mix vermilion or scarlet with a touch more orange and lighten it until it stops reading as red and starts reading as coral.

The trap is stopping too soon. Coral needs more water than most reds feel comfortable with, and the temptation is always to keep it dark and rich instead of letting it go pale and warm. Push past where a red would normally stop, then stop.

Mix	Recipe	Best for
Coral from scratch	Pyrrole orange, lightened with water	Sunsets, flowers, warm skies
From a red	Vermilion or scarlet, warmed with a touch more orange and lightened with water	When there is no dedicated orange in the box
Rose route	A warm red with a rose pigment mixed in, then diluted well	Skin in warm light, a softer, pinker coral
Opaque version	Any of the above lightened with white instead of water	Flowers, ceramics, anything that should read as solid rather than washed
Pale wash	Any coral mix, heavily diluted	A blush of color across skin or an evening sky

Closest mix from the Tobio's kit

Sunset Orange and Electric Rose, roughly two to one, get you there fast, since one is already orange and the other a cool pink that softens it. Lighten it with Titanium White or plenty of water until the mix stops reading as a hot red and starts reading as coral: pale, warm, a little dusty. Test on scrap first. Too little water and you have made a sunset instead of the stone it is named after.

The 12-color kit does not include a tube of coral, so this is how I get there with what is in the palette. Running low on a color? The 12 paint refills drop straight into the wells.

Using coral in watercolor

Coral earns its keep in skin painted in warm light, in sunsets, and in flowers, anywhere a color needs to sit between red and orange without turning fully into either one. It is a color for warmth rather than drama.

Wet-on-wet, it spreads into a soft blush that suits a cheek or a dusk sky far better than a hard edge would. On dry paper it holds its shape well enough for petals, where a crisp boundary between coral and its neighbor actually helps the flower read correctly.

It sits well against a true green, its rough opposite on the wheel, and against a warm cream that keeps it from looking too saturated sitting on its own.

One thing I learned the hard way: coral drifts toward salmon if too much white creeps in, and salmon reads as flat rather than warm. Keep it thinner rather than paler if you want it to stay coral instead of turning into something closer to a bandage.

Everything I use on this page is the Tobio's Watercolor Kit: twelve colors chosen to mix, a walnut palette, cotton paper, and a water brush. Want to see how any two of the colors blend before you commit? Try the interactive color mixing chart.

Coral vs salmon (and peach)

Salmon is the color people confuse coral with most, and the two are close enough that the difference comes down to saturation rather than hue. Coral stays warm and a little intense, closer to the stone at full strength. Salmon is the same family pushed toward gray, named for the fish rather than the reef, and it reads as softer and less certain of itself on the page.

Peach is the paler, yellower cousin of both. Where coral leans toward red, peach leans toward a warm yellow-pink with almost no red left in it at all. Put the three side by side on a strip of paper and coral is clearly the boldest of the group, the one that still argues for attention instead of receding into a background wash.

If coral is a sunset low on the horizon, salmon is the same sky an hour later, and peach is the color it turns just before the light finally goes.

Questions people ask

What is the coral color hex code?

On screens, coral color is #FF7F50, a warm orange-pink partway between red and orange. Paint versions run duller than the screen value, closer to the stone's own deep pink-red than to the bright web swatch.

Is coral warm or cool?

Warm. It carries orange rather than blue, and the added lightness only makes the warmth more obvious. It sits close to skin tones and sunsets for exactly that reason.

What colors make coral?

A warm red lightened with orange and water, or a pyrrole orange used alone. From the Tobio's kit, Sunset Orange and Electric Rose, roughly two to one, lightened with Titanium White or plenty of water.

Is coral toxic?

No. The pyrrole and rose pigments used to mix coral today carry no heavy metals, unlike some of the older reds a painter might once have reached for instead.

Why is coral called coral?

It is named after the red coral of the Mediterranean, Corallium rubrum, harvested and carved into jewelry since antiquity. The word was first recorded as a color name in English in 1513, long after the material itself was already being traded.

Coral vs salmon, what is the difference?

Coral is warmer and more intense. Salmon is the same family pushed toward gray, named after the fish rather than the reef. Coral reads as a sunset, salmon reads as its faded, cooler cousin.
