Somewhere in the middle of all these colors is a pure blue, uninfluenced by either of the other two primaries — a blue containing no red and no yellow. Of all the blue watercolor pigments we use, Cobalt is the closest to a pure primary blue, however it is a weak, transparent pigment and is easily overpowered when mixed with other colors so we need a selection of blues to be able to mix a full range of colors.
It will cool down a background, pushing it way back into the distance. The first wash is made up of several layers of French Ultramarine Blue — each applied after the preceding wash dried. The second example shows the same method used with Cobalt Blue. The Ultramarine pigment has filled the papers texture and is starting to go streaky. The Cobalt wash remains flat and even. Ultramarine Blue is a warm blue containing traces of red. It sits towards Violet on the color wheel.
Ultramarine is a strong, sedimentary pigment and mixes well with other colors to make rich strong darks, subtle greys or mauves. It can be used to mix dirty, compound greens, but, because it contains traces of red, it will not mix a strong, saturated green. French Ultramarine Blue is more intense than Ultramarine Blue. It is usually more expensive, but lasts much longer, is much better to mix with and, in the long run, is better value than regular Ultramarine. Moving to the yellow influenced blues, Phthalo Blue watercolor is probably the most intense.
It is a strong stain and will bleed up through any colors placed over it. It can be used to mix vibrant, saturated greens or strong darks. Not being sedimentary means Phthalo Blue can be built up gradually by applying a number of pale washes. Winsor Blue green shade is very similar. Prussian Blue and Antwerp Blue are also yellow influenced blues but lack the purity and intensity of Phthalo or Winsor.
The Color That Changed the World
Green or Yellow shade is the best choice to fill the cool side of the blue spectrum. The staining power of Phthalo Blue can be seen here. The Phthalo bleeds up, even through the heavy, opaque gouache. Cerulean is similar in color to dilute Phthalo but much less intense.
Turquoise is a handy accent color, but behaves a little like gouache.Quick Tip 124 - Warm Blue/Cool Blue
A similar result can be achieved by mixing Phthalo and Aureolin with some white gouache.It's a color conundrum: Can you use a different blue for a limited-palette project if phthalo blue isn't a color you already have? It would be churlish to say no; if you don't have phthalo blueyou may substitute ultramarine.
Ultramarine is the best alternative because that color is also a transparent pigment with a good tinting strength. Cobalt is transparent but has a weak tinting strength, and cerulean blue is only semitransparent, also with a weak tinting strength. The disadvantage of ultramarine blue over phthalo blue, though, is that it doesn't make as deep of a dark shade on its own.
But first check that you don't have phthalo blue lurking around under one of its other names, such as thalo blue, monestial blue, Winsor blue, monastral blue, phthalocyanine blue, intense blue, Old Holland blue, or Rembrandt blue. Check the label to see if the tube contains PB 15, and then you've got phthalo blue. Ultramarine pigment was first created by grinding up the semiprecious stone lapiz lazuli, found in Afghanistan and Chile.
Used in Afghanistan since the 6th century, its most widespread European use happened in the late Middle Ages of the 14th and 15th centuries. Italian panel paintings and illuminated manuscripts featured the pigment, which was imported there via Venice. Its use required the deep pockets of the church; European artists there couldn't afford it, as its rarity demanded a premium to say the least.
In Johann Wolfgang von Goethe knew of an ultramarine substitute that was created by scraping a blue residue off lime kiln walls near Palermo, Italy. Because the real ultramarine blue pigment was so expensive, pursuit of an artificial substitute was well documented, and a prize was offered to chemists who could come up with a compound resembling the chemical composition of the real thing.
Artificial ultramarine pigment was ultimately first synthetically produced in the s in Europe from china clay, sodium carbonate, and sulfur, plus some silica and rosin. Marion Boddy-Evans. She has written for art magazines blogs, edited how-to art titles, and co-authored travel books. Chemically, it's composed of rings of nitrogen and carbon atoms around a copper atom.Any artist who enjoys using Prussian blue will find it hard to imagine that such a beautiful blue was actually the result of an experiment gone wrong.
The discoverer of Prussian blue, the colormaker Diesbach, was in fact not trying to make a blue, but a red. The creation of Prussian blue, the first modern, synthetic color was completely accidental. Diesbach, working in Berlin, was attempting to create cochineal red lake in his laboratory.
The ingredients he needed were iron sulfate and potash. In a move that'll bring a smile to any artist's who's ever tried to save money by buying cheap materials, he obtained some contaminated potash from the alchemist in whose laboratory he was working, Johann Konrad Dippel. The potash had been contaminated with animal oil and was due to be thrown out. When Diesbach mixed the contaminated potash with the iron sulfate, instead of the strong red he was expecting, he got one that was very pale.
He then attempted to concentrate it, but instead of a darker red he was expecting, he first got a purple, then a deep blue. He'd accidentally created the first synthetic blue pigment, Prussian blue. It's hard to imagine now, given the range of stable, lightfast colors we can buy, that in the early eighteenth century artists didn't have an affordable or stable blue to use.
Ultramarine, which is extracted from the stone lapis lazuli, was more expensive than vermilion and even gold.
In the Middle Ages, there was only one known source of lapis lazuli, which means simply 'blue stone. Other deposits have subsequently been found in Chile and Siberia. Indigo had a tendency to turn black, was not lightfast, and had a greenish tinge. Azurite turned green when mixed with water so couldn't be used for frescoes. Smalt was difficult to work with and had a tendency to fade. And not enough was yet known about the chemical properties of copper to consistently create a blue instead of a green it's now known that the result depends on the temperature it was made at.
Neither Diesbach nor Dippel was able to explain what had happened, but these days we know that the alkali the potash reacted with the animal oil prepared from bloodto create potassium ferrocyanide. Mixing this with the iron sulfatecreated the chemical compound iron ferrocyanide, or Prussian blue.
Diesbach made his accidental discovery sometime between and In it was described as being "equal to or excelling ultramarine". Being about a tenth of the price of ultramarine, it's no wonder that by it was being widely used across Europe. By Winsor and Newton were selling Prussian blue and other paints based on it such as Antwerp blue Prussian blue mixed with white.
Prussian blue is a translucent semi-transparent color but has a high tinting strength a little has a marked effect when mixed with another color. Originally Prussian blue had a tendency to fade or turn grayish green, particularly when mixed with white, but with modern manufacturing techniques, this is no longer an issue. Marion Boddy-Evans.
She has written for art magazines blogs, edited how-to art titles, and co-authored travel books. Updated March 08, Prussian bluealso known as Berlin blue, is a dark blue colour that is artificially made. It is one of the first pigments made synthetically. It was accidentally found in by two chemists in Berlin. The dark blue uniforms of the Prussian army were dyed this colour. A colour can be shown by hex triplet is a six- digitthree- byte hexadecimal number used in HTMLCSSand other computing applications.

How to Make Prussian Blue Ink
Prussian blue is a chemical compound. One of the chemical elements in this compound is iron. Researchers have experimented replacing some of the iron atoms in Prussian blue with cobalt. When the Prussian blue compound is lit with a red light at Cthe compound shifts from being non-magnetic off to magnetic on.
The magnetic shift does not change back except if deliberately reversed or undone with heat. This magnetism is due to the transfer of an electron from the cobalt to the iron, with light providing the energywhile the electron moves back when heat is applied, the researchers said.
This magnetic property means the compound can be used in computer storage.
Because the compound can be turned " on " and " off " in a controlled way, it can remember binary information. Binary information is used for computer storage. This way of using the compound is still being developed. From Wikipedia, the free encyclopedia. This box shows the colour Prussian blue. Retrieved January 18, Emergency Preparedness and Response.

Black is a commonly used paint color, but you may not have any on hand or you may want a black that leans slightly toward another color. Black paint can be made with equal parts red, yellow, and blue paint mixed together on a palette.
You can also mix complementary colors such as blue and orange, red and green, or yellow and purple. Mixing blue and brown can also result in a rich black.
An artist color mixing guide
To make black paint, first mix blue paint with a tiny bit of red paint. Keep adding tiny amounts of red to the blue until you have a deep, dark purple color. Then, mix in a tiny bit of yellow paint. Test the color on a white piece of paper. You can also add more blue to make the black darker. To make black food coloring, just mix 2 parts blue food coloring with 3 parts red food coloring and 5 parts green food coloring.
