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.
Primary Colours (Eddy Current Suppression Ring album)
Primary Colours is the second album by Australian garage punk band Eddy Current Suppression Ring. The album was recorded in a suburb of Melbourne over a 24-hour period in August 2007. The album was first released on Aarght! Records in Australia only on 5 May 2008, then on 9 September 2008 on Goner Records in the United States, and finally in the United Kingdom on Melodic Records on 17 August 2009. "Which Way to Go" was the only single released from "Primary Colours". "Primary Colours" peaked at No. 13 on the ARIA Hitseekers Chart in June 2008. It received generally positive reviews from critics, who praised the album's minimalistic sound and warm, personable lyrics.
Military colours, standards and guidons
In military organizations, the practice of carrying colours, standards or guidons, both to act as a rallying point for troops and to mark the location of the commander, is thought to have originated in Ancient Egypt some 5,000 years ago. The Roman Empire also made battle standards a part of their vast armies. It was formalized in the armies of Europe in the High Middle Ages, with standards being emblazoned with the commander's coat of arms. As armies became trained and adopted set formations, each regiment's ability to keep its formation was potentially critical to its, and therefore its army's, success.
Evolution of human colour vision
Evolution of human colour vision over time: humans ("homo sapiens") have developed a trichromatic view of the world in comparison to a majority of other mammals that only see the world from a dichromatic view. Early human ancestors are believed to have viewed the world using UV vision as far back as 90 million years ago. It is thought that the shift to trichromatic vision capabilities and the ability to see blue light have evolved as an adaptive trait over time. It is believed that due to a number of environmental factors, ancestral humans lived with limited colour vision. This is believed to have also been influenced by life styles, including being predominantly nocturnal.
Holi
Holi (; "Holī") is a Hindu spring festival celebrated in the Indian subcontinent, also known as the "festival of colours" or the "festival of love". The festival signifies the victory of good over evil, the arrival of spring, end of winter, and for many a festive day to meet others, play and laugh, forget and forgive, and repair broken relationships. It is also celebrated as a thanksgiving for a good harvest. It lasts for a night and a day, starting on the evening of the Purnima (Full Moon day) falling in the Vikram Samvat Hindu Calendar month of Phalguna, which falls somewhere between the end of February and the middle of March in the Gregorian calendar.
Chromoxylography
Chromoxylography was a colour woodblock printing process, popular from the mid-19th to the early-20th century, commonly used to produce illustrations in children's books, serial pulp magazines, and cover art for yellow-back and penny dreadfuls. In the 19th century the art of relief engraving and chromoxylography was perfected by engravers and printers, most notably in England by Victorian engraver and printer Edmund Evans. A wide range of hues and tones were produced by the color mixing of the chromoxylography process—a technique that was complicated, requiring intricate engraving and printing for good results.
History of painting
The history of painting reaches back in time to artifacts from pre-historic humans, and spans all cultures. It represents a continuous, though periodically disrupted, tradition from Antiquity. Across cultures, and spanning continents and millennia, the history of painting is an ongoing river of creativity, that continues into the 21st century. Until the early 20th century it relied primarily on representational, religious and classical motifs, after which time more purely abstract and conceptual approaches gained favor. Developments in Eastern painting historically parallel those in Western painting, in general, a few centuries earlier.
