Blue is a universally popular color. Many people love this color, and there are solid reasons for it.
Blue is a color which is mostly preferred by men. The blue color is widely found in nature, the blue sky, the oceans, some kinds of birds and flowers. There is a lot to be discussed about this color.
Even if blue isn’t your favorite color yet, this article will give you enough reason to reconsider your opinion.
Ow, come on, what could possibly make you don’t like this color?

Then, let’s waste no more time and get started.

How to obtain blue color?

One of the resources to obtain blue dye from, is Lapis lazuli, which is obtained by mining its stone: Lapis lazuli ore. Blue dye can be extracted from minerals such as cobalt and azurite. These stones are crushed and ground into powder, then mixed with drying binding agents and left to dry. This is the process of obtaining blue dyes.
Natural resources also provide blue dye. In Europe, people used plants like woad to extract blue pigments; in Asia and Africa: Indigofera tinctoria was used to make blue dyes.

Blue is one of the three primary colors in color theory. On the spectrum of visible light, blue is between violet and green. And its wavelength is between 450-490 nm.
Most blues contain a slight mixture of other colors; azure contains some green, while ultramarine contains some violet.

Blue dye

There are plenty of natural and mineral resources to provide us with blue dye and pigments. Since the 18th century, blue dye has mostly been obtained from the chemical and synthetic process.
Blue, just like any other color, has various shades and hues. Hues of blue that are closer to violet include indigo and ultramarine. There is pure blue, which as the name suggests it is pure and without any mixture of other colors.
The last one is cyan, which is midway in the spectrum between blue and green, and the other blue-greens turquoise, teal, and aquamarine. 

Have you ever wondered why the sky and the oceans seem blue?
the answer is the Rayleigh scattering.

Now, what is the Rayleigh scattering?
In the visible spectrum of light, blue color has a very short wavelength, while red color has the longest. When the sunlight gets through the atmosphere, the wavelengths of blue are scattered more widely by two molecules: oxygen and nitrogen. This is why more blue color comes to our eyes, and we see the sky and the sea blue.
This effect is named after the scientist who discovered it; the British physicist Lord Rayleigh. Also, Einstein confirmed it in 1911.

Blue in history

Compared to all the other colors like red, green or brown for example, the blue color is quite a latecomer. there is no blue in ancient cave paintings.
Also, in language and literature, the word Blue was not very old.
More than 3000 years ago, in Afghanistan, Lapis lazuli was mined and exported to other parts of the ancient world. Egyptians were one of the biggest consumers of blue dyes in ancient times. but, since exporting this semi-precious stone was expensive, Egyptians had to make their own blue dyes and pigments. Therefore, about 2500 years ago, Egyptians started to produce Egyptian Blue. They used resources like silica, lime, copper, and alkali. they produced the first synthetic dyes by grinding the above-mentioned stones and heating them to 800-900 °C. 

Blue in ancient world

In Iran, Lapis lazuli stone was used to make jewelry and vessels.
In ancient Egypt, it was used for the eyebrows on the funeral mask of King Tutankhamun. . It was particularly used in funeral statuary and figurines and in tomb paintings. They believed that blue would protect the dead against the evil in the afterlife. blue was associated with the sky and divinity in Egypt (also known as the eye of god).

Egyptians and Iranians are not the only people who lived in the ancient world. Surpriseee, ancient Greeks.
Ancient Greeks categorized colors based on being light or dark; rather than the hue. the word for all these colors:
dark blue, dark green, violet, black, and brown, is Kyaneos. Yeah a bit confusing! The Greeks imported indigo dye from India, calling it Indikon.

I wish we had more time to cover more history, but we still have a lot to talk about. So, it is now time to move on….

About Blue

Blue color (all colors) has different hues and shades. There is dark blue and light blue. Their accent is mutual, but they transmit rather different emotions and meanings. Dark blue is kind of associated with strong and foreboding concepts (imagine dark clouds), while light blue is a gentler and more optimistic color. Light blue brings a sense of purity and serenity. 

Just close your eyes and think of a clear and blue sky in the middle of summer…How warm and relaxing!! Blue as the most common color in nature ( yeah I know, green too) can help you take meaningful photos and convey feelings of peace and quietness.

What is a blue filter in photography?

Blue filters are not very common in black and white photography, because they lighten the sky and darken highlights or colors that appear light.
