Malachite

Malachite is a banded green copper mineral, and malachite pigment, ground from the stone, is about as old as paint gets: Egyptians were grinding it for eye paint before 3000 BC. Today it is a gemstone first and a watercolor almost never.

Warm or coolCool to neutral. The web chip leans a hair yellow, but the mineral sits nearer blue-green, so a mixed mineral green wants a touch of blue, not yellow.
On the wheelA green just on the yellow side of true green, bright as a traffic light. That is the 1930 dictionary color the web uses; the stone is a deeper, bluer green with pale bands.

The story of malachite

Malachite is the first green anyone painted with, and the first thing they painted was their own eyelids.

The stone is copper carbonate, banded light and dark like tree rings, and it weathers out of copper ore wherever copper is. Egyptians were digging it near Suez and in the Sinai by 4000 BC. Before they had pharaohs they had makeup palettes, small slabs of gray-green stone shaped like fish and turtles, and the pigment most often found on them is malachite. It went on the lower lid, with black galena on the upper, against sun glare and infection, and traces of it are still on the faces of bodies at Adaima. Green, wadj, meant growth and rebirth, and the Egyptian paradise was the Field of Malachite. Cleopatra is recorded using it on her eyes.

The museum says what these were for: grinding eye paint, green from malachite or black from galena, worn against sun glare and infection. Five thousand years old, and it is a makeup palette. The Cleveland Museum of Art, CC0.

China loved it just as long. Warring States bronzes were inlaid with powdered malachite and azurite, and from the 400s BC the official palette settled on two minerals: azurite for blues, malachite for greens. That pairing became the blue-and-green landscape, mountains laid in as flat opaque color to mean paradise or the ancient past, and it carried into Japan, where mineral paints are still graded by grain. Coarse grains stay dark and saturated; fine grains scatter light and go almost white. Tibetan monks ground it coarse on purpose.

Rocks drawn in ink and filled with opaque blue and green mineral pigment, a way, the museum says, of pointing at paradise or the past. That flat, solid green is ground stone, not a wash. The Cleveland Museum of Art, CC0.

Europe used it too. Irish and other monks laid it into manuscripts for their brightest greens, always pure, because in a mixture it went unstable, and Raphael's green curtain behind the Sistine Madonna is malachite. It cost a fortune then and costs one now, over a hundred euros for a hundred grams in 2000. Verdigris, made rather than mined, and green earth, dug by the cartload, did the everyday work. Around 1800 the factories arrived, first a synthetic copper carbonate sold as verditer, then chrome green and the arsenic greens, and malachite left the paint box for the jewelry box.

The jewelry box is where the word lives now. Russian tsars veneered whole rooms in Ural malachite, the Hermitage has a Malachite Room, and under Nicholas I slabs of the stuff were a favorite diplomatic gift. The base of the World Cup trophy is two layers of it. Search the name and you get bracelets, which is fair; the stone is what people see.

Here is the thing I keep coming back to. The web color called malachite is a bright sports-drink green from a 1930 color dictionary, and it looks nothing like the stone. The stone is a deep, slightly blue green with pale rings, closer to a bottle than a lime. When I want malachite in a painting I am chasing the rock, not the swatch.

Pigment facts

Colour IndexPG39 in the Colour Index: natural basic copper carbonate, Cu2CO3(OH)2, the same stuff as the stone. This page describes the historical pigment, which left everyday paint boxes around 1800; if a tube says malachite today, look for PG39 on the label.
TransparencySemi-opaque to opaque. Ground coarse it covers; ground fine it goes pale and chalky, which is why old painters kept it coarse.
LightfastnessModerate. It is sensitive to acids and shifts color with time, and painters never mixed it, because in a mixture it went unstable.
GranulationHeavy. It is a ground rock, and the coarse grades sit in the tooth of the paper like sand.
StainingNone. Coarse mineral particles sit on the surface and lift with a damp brush; the color stays put or comes off entirely.
ToxicityA copper compound. The polished stone is harmless to hold; the dust from grinding it is not. Egyptians wore it on their eyelids, which is not a recommendation.

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

How to mix malachite

There are two malachites to mix; decide which you want before you wet the brush. The web chip is a bright yellow-leaning green: a green-leaning blue and a warm yellow, about equal. The mineral is a deep blue-green with lighter bands: start from a dark green, push it toward blue, then lift the bands out with water. The pairing that matters is green and a cool red. A speck of a crimson like Poppy Bloom takes the toy out of any bright green and makes it look dug up rather than bought.

Phthalo green does malachite's old job today, and it needs the same correction, only more of it.

Closest mix from the Tobio's kit

Forest Green with a little Glacier Blue, about four to one, gives the deep blue-green of the stone. For the pale bands add Titanium White to part of the puddle and drag it through the dark in stripes while it is wet. If it looks like a Christmas tree, a speck of Poppy Bloom calms it. For the bright web chip, Glacier Blue and Lemon Yellow, half and half, with a touch of Green Gold. Test on scrap first.

The 12-color kit does not include a tube of malachite, 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 malachite in watercolor

Use the mineral version for anything meant to look dug out of the ground: the stone in a still life, moss on a wall, deep foliage in shade, an old bronze. Use the bright web version for one lit leaf or a parrot's wing, never a whole tree.

The technique worth stealing is the scroll painters' one. Draw the shape in ink, let it dry, then fill it with green laid flat and thick, one pass, no fussing. The flatness is the point; a hard-edged wash reads as stone in a way a soft one never does.

It pairs with a deep blue and a hot red. The old Chinese palette set azurite beside malachite, and Twilight Indigo with Glacier Blue beside your green does the same job.

One thing I learned the hard way: the bright chip takes over. A saturated yellow-green pulls the eye from across a room, and a landscape full of it looks like a soda advertisement. Gray it with a speck of red and save the pure color for a fingernail-sized spot.

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.

Malachite vs emerald green (and phthalo green)

All three are copper greens, and that is where the resemblance ends. Malachite is the stone, dug, ground and laid on coarse: a deep green with a blue cast, weak in tint, opaque, expensive, and stable if nobody mixes it. It was the precious green, for small patches in manuscripts and whole mountains in Chinese scrolls.

Emerald green was the 1800s answer, copper married to arsenic: brilliant, and poisonous enough to double as a pesticide. It replaced malachite and verdigris in a generation. Phthalo green is the modern one, a copper phthalocyanine from a laboratory, transparent, staining, and so strong a fingernail of it colors a bucket of water.

If malachite is a bottle of green glass held up to the light, emerald green is the same bottle with a skull on the label, and phthalo green is a laser pointer.

Questions people ask

What color is malachite?
On screen, a bright yellowish green, hex #0BDA51, from Maerz and Paul's 1930 color dictionary. The stone is different: a deep, slightly blue green banded with paler rings, closer to bottle glass than to a lime.
Is malachite warm or cool?
Cool to neutral. The web chip leans a hair toward yellow, but the mineral leans toward blue, so when painting the stone add a touch of blue to your green, not yellow.
What colors make malachite?
For the stone, a deep green with a little green-leaning blue. From the Tobio's kit, Forest Green and Glacier Blue, four to one, with Titanium White dragged through for the rings and a speck of Poppy Bloom to calm it.
Is malachite toxic?
A copper compound. The polished stone is safe to handle, but dust from grinding it releases soluble copper, and water that has stood on malachite should not be drunk. Genuine malachite is not in modern watercolor boxes.
Is malachite green the same as malachite?
No. Malachite green is a synthetic triarylmethane dye used on silk, leather and paper and, controversially, as an antimicrobial in fish farming. It was named for its color and contains no malachite; the mineral is copper carbonate.
Why did painters stop using malachite?
Cost, mostly: over a hundred euros for a hundred grams in 2000. It went unstable in mixtures, had to stay coarse to keep its color, and around 1800 verditer and then chrome green took over; China still uses it for fine greens.
