Blue is so beautiful. Lapis lazuli is a beautiful shade of blue. 
The semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and later, in The Renaissance, to make the pigment ultramarine, the most expensive of all pigments.

Lapis lazuli
Lapis lazuli (, ), or lapis for short, is a deep blue metamorphic rock used as a semi-precious stone that has been prized since antiquity for its intense color. As early as the 7th millennium BC, lapis lazuli was mined in the Sar-i Sang mines, in Shortugai, and in other mines in Badakhshan province in northeast Afghanistan. Lapis was highly valued by the Indus Valley Civilisation (3300–1900 BC). Lapis beads have been found at Neolithic burials in Mehrgarh, the Caucasus, and even as far from Afghanistan as Mauritania. It was used in the funeral mask of Tutankhamun (1341–1323 BC). At the end of the Middle Ages, lapis lazuli began to be exported to Europe, where it was ground into powder and made into ultramarine, the finest and most expensive of all blue pigments.
Blue
Blue is one of the three primary colours of pigments in painting and traditional colour theory, as well as in the RGB colour model. It lies between violet and green on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colors; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called Tyndall scattering explains blue eyes.
List of Deltora Quest characters
The "Deltora" series features a wide line of characters, both important and minor. The series also features many different monsters and creatures that appeared in all of the many different books. This article is a list of the many different characters and creatures that have appeared in the Deltora series. Lief was raised as a blacksmith's son in the run-down city of Del after the invasion. Hot-headed and impatient at the start of the series, all he wanted to do was go out and explore the city. On the night of his sixteenth birthday, he leaves on his father's quest to restore the Belt of Deltora, the only thing that can save their land and the heir from the tyranny of the Shadow Lord.
Blue–green distinction in language
Many languages do not distinguish between what in English are described as "blue" and "green" and instead use a cover term spanning both. To describe this English lexical gap, linguists use the portmanteau word "grue", from "green" and "blue", which the philosopher Nelson Goodman coined in his 1955 "Fact, Fiction, and Forecast" to illustrate the "new riddle of induction". The exact definition of "blue" and "green" may be complicated by the speakers not primarily distinguishing the hue, but using terms that describe other color components such as saturation and luminosity, or other properties of the object being described.
Azure (color)
Azure ( ) is a variation of blue that is often described as the color of the sky on a clear day. On the , "azure" (color #007FFF) is defined as the color at 210 degrees, i.e., the hue halfway between blue and cyan. In the RGB color model, used to create all the colors on a television or computer screen, azure is created by adding a little green light to blue light. The complementary color of azure is orange. In the X11 color system which became a standard for early web colors, azure is depicted as a pale cyan. The color azure ultimately takes its name from the intense blue mineral lapis lazuli. '
Ultramarine
Ultramarine is a deep blue color and a pigment which was originally made by grinding lapis lazuli into a powder. The name comes from the Latin "ultramarinus", literally "beyond the sea", because the pigment was imported into Europe from mines in Afghanistan by Italian traders during the 14th and 15th centuries. Ultramarine was the finest and most expensive blue used by Renaissance painters. It was often used for the robes of the Virgin Mary, and symbolized holiness and humility. It remained an extremely expensive pigment until a synthetic ultramarine was invented in 1826. The pigment consists primarily of a zeolite-based mineral containing small amounts of polysulfides.
Royal Cemetery at Ur
The Royal Cemetery at Ur is an archaeological site in modern-day Dhi Qar Governorate in southern Iraq. The initial excavations at Ur took place between 1922 and 1934 under the direction of Leonard Woolley in association with the British Museum and the University of Pennsylvania Museum of Archaeology and Anthropology in Philadelphia, Pennsylvania. The process was begun in 1922 by digging trial trenches, in order for Woolley to get an idea of the layout of the ancient city. In one trench where initially nothing was discovered, head archaeologist Leonard Woolley decided to dig deeper. There, clay vases, limestone bowls, small bronze objects and assorted beads were found.

Color wheel
A color wheel or colour circle is an abstract illustrative organization of color hues around a circle, which shows the relationships between primary colors, secondary colors, tertiary colors etc. Some sources use the terms "color wheel" and "color circle" interchangeably; however, one term or the other may be more prevalent in certain fields or certain versions as mentioned above. For instance, some reserve the term "color wheel" for mechanical rotating devices, such as color tops or filter wheels. Others classify various color wheels as "color disc", "color chart", and "color scale" varieties.
Shades of green
Varieties of the color green may differ in hue, chroma (also called saturation or intensity) or lightness (or value, tone, or brightness), or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a green or other hue mixed with white, a shade being mixed with black. A large selection of these various colors is shown below. Green is common in nature, especially in plants. Many plants are green mainly because of a complex chemical known as chlorophyll which is involved in photosynthesis. Many shades of green have been named after plants or are related to plants.
