How to Mix Cobalt Blue

Learning the art of mixing colors is a necessity for any artist. Most artist painting kits come with a selection of basic colors. The kits typically contain cadmium yellow, cadmium red, phthalo green, ultramarine blue, titanium white and mars or ebony black. Most artists need a wider range of colors for paintings or crafts. If you want to make a color like cobalt blue, purchase ultramarine blue or a kit, and buy a separate tube of turquoise blue. When you mix these colors correctly, the paint turns a bright cobalt blue.

Step 1

Thin the ultramarine blue in one mixing container, and thin the turquoise blue in another mixing container. If you use water-based paint, thin it with water. If you use another type of paint, use the appropriate thinner for the medium you use. Make it thin enough so it is easily mixed.

Step 2

Add three parts ultramarine blue paint to the container, and add one part turquoise blue. Add the paint in any order, as long as you keep the ratio correct. If you mix the paint in a small batch, use teaspoons for measuring the colors. If you mix a large batch, use a cup. Stir the paint thoroughly. If it isn’t light enough, mix in a little bit of turquoise blue.

Step 3

Test the paint on a piece of paper. Let it dry thoroughly. Check the color. If it’s too dark, add more turquoise blue. If it’s too light, add a little more ultramarine blue.

Tip

See how many colors of blue come from ultramarine blue and turquoise blue. Put a piece of paper on a table. Put a dab of ultramarine blue and a dab of turquoise blue on the paper, and write a plus sign between the two. Write an equal sign after the second color. Mix one part ultramarine blue to one part turquoise blue, and put a dab of the color after the equal sign. Add another dot of turquoise, stir and put a dot of color on the paper. Continue adding dots of turquoise and putting dots of the color on the paper. Start a second line under the mixed colors. Mix one dot of ultramarine blue and turquoise blue. Add a dot of ultramarine blue at a time, and put a dab of each color across the line.

The Color Cobalt Blue Pigments Through The Ages

Although smalt, a pigment made from cobalt blue glass has been known at least since the Middle Ages, the color cobalt blue established in the nineteenth century was a greatly improved one.

The isolation of the blue color of smalt was discovered in the first half of the eighteenth century by the Swedish chemist Brandt. In 1777, Gahn and Wenzel found cobalt aluminate during research on cobalt compounds. Their discovery was made during experimentation with a soldering blowpipe. The color was not manufactured commercially until late in 1803 or 1804.

The Minister of the French government, Chaptal, appointed Louis Jaques Thénard and Mérimée to look into the improvement of artists’ colors. Thenard developed this new cobalt blue by his observations at the Sevres porcelain factory. He experimented with roasting cobalt arsenate and cobalt phosphate with alumina in a furnace. He published his results in late 1803-4 in the Journal des mines, “Sur les couleurs, suives d’un procédé pour préparer une couleur bleue aussi belle que l’outremer.”

Thénard tried the blue in oil and gum media and by the time his report was published, the color had not changed after a two-month exposure test. Production began in France in 1807. Most sources cited regard Thenard as the inventor of the blue. However, Leithner of Vienna is also mentioned as one who developed cobalt arsenate as early as 1775.

Cobalt blue was generally regarded as durable in the nineteenth century. It requires one hundred percent of oil to grind it as an oil paint otherwise its cool tone can turn greenish due to the yellowing of linseed oil. To avoid the yellowing, Laurie suggested that it be used as a glaze color or mixing it with white. It is totally stable in watercolor and fresco techniques. Field called it a “modern, improved blue”. John J. Varley, author of List of Colours, recommended it as a good substitution for ultramarine blue for painting skies.
