Where does blue pigment come from?

Blue pigments were traditionally manufactured from minerals such as lapis lazuli, cobalt, and azurite, while blue dyes were initially derived from plants, most commonly woad in Europe and Indigofera tinctoria, or real indigo, in Asia and Africa. Most blue pigments and dyes are now produced chemically.

Lapis lazuli is the name given to a group of dark blue minerals with a metallic luster that change color when heated. The best-known member of this group is malachite, which is used for making green and blue plates. Other members include azurite and chrysocolla. Malachite comes in many different colors and varieties. It was historically used as a pigment but is now replaced almost entirely by synthetic products. There are still mines that produce malachite, however.

Cobalt occurs in nature in the form of dark blue crystals. It is used in medicine as an analgesic and to treat nerve disorders. As a pigment it has been used since ancient times for painting objects such as statues and ceramics. It can also be found today in some paints and cosmetics.

Azurite is a blue mineral that changes color when heated. Like other azure minerals, it is used as a pigment. In antiquity, people believed that it had magical properties and used it in love potions and spells. It is still used today in some medicines due to its healing properties.

Where does the color blue ink come from?

Indigo colors were called after India, where they were discovered and spread along the Silk Road. Blue ink was traditionally sourced from the indigo plant, but it is now mostly synthetic. Ink blue's rich past provides it a traditional aspect and makes it a welcome complement to any home palette.

In addition to being used for writing, blue ink was also used as a blood stain indicator during meditative practices and in rituals devoted to death and mourning. This is because when blue ink is printed on white paper, it stains the paper blue.

The ancient Chinese invented blue pigment around 200 B.C., which led them to use it for calligraphy brushes, painting clothes, and jewelry. It took another 500 years before it was adopted widely in Europe for similar purposes.

Today, the main ingredient in blue ink is cobalt oxide, which is mixed with other substances to change its color. The most common red ink contains copper sulfate, while green includes copper acetate. Brown is made up of iron oxides, while black is carbon.

Blue has many different meanings in various cultures. In Christianity, it can refer to the Holy Spirit or the Sky God. In Judaism, it represents wisdom and eternity. In Islam, it stands for faith, hope, and love.

In modern times, blue means frustration and disappointment to some people.

Where does the blue in blue dye come from?

Indigo leaves, dyer's knotweed (Japanese indigo) leaves, and first-year woad rosettes are sources of natural blue dyes. (Only first-year woad rosettes are utilized since older plants have less blue to extract.) Indigofera tinctoria, also known as Indian berry or devil's paintbrush, is a flowering plant in the legume family (Fabaceae). The leaves and stems contain an alkaloid called indigo, which under the right conditions can be converted into blue dyes. Although not widely used today, blue was once one of the most popular colors in the world.

In 1721, Charles Joseph Vernet invented a process for making blue color by using indigo as a source. This was two years before Isaac Newton discovered how to make red colors by using cochineal insects. Until then, these were all colors that had to be extracted from nature or produced by synthetic means.

Newton's work established a new standard for color production. It became important because prior to this time, there were no permanent pigments available. All colors were made by mixing variously intense shades of white or black. In 1856, William Henry Perkin improved on Vernet's technique by introducing chromium into the equation. This new color, called "Prussian blue", was a deep, stable, transparent azure.
