Yellow is the color between green and orange on the spectrum of visible light. It is evoked by light with a dominant wavelength of roughly 570–590 nm. It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity. Carotenoids give the characteristic yellow color to autumn leaves, corn, canaries, daffodils, and lemons, as well as egg yolks, buttercups, and bananas. They absorb light energy and protect plants from photodamage. Sunlight has a slight yellowish hue, due to the surface temperature of the sun.
Because it was widely available, yellow ochre pigment was one of the first colors used in art; the Lascaux cave in France has a painting of a yellow horse 17,000 years old. Ochre and orpiment pigments were used to represent gold and skin color in Egyptian tombs, then in the murals in Roman villas. In the early Christian church, yellow was the color associated with the Pope and the golden keys of the Kingdom, but was also associated with Judas Iscariot and was used to mark heretics. In the 20th century, Jews in Nazi-occupied Europe were forced to wear a yellow star. In China, yellow was the color of the Middle Kingdom, and could be worn only by the Emperor and his household; special guests were welcomed on a yellow carpet.
According to surveys in Europe, Canada, and the United States, yellow is the color people most often associate with amusement, gentleness, humor, and spontaneity, but also with duplicity, envy, jealousy, avarice, and, in the U.S., with cowardice. In Iran it has connotations of pallor/sickness, but also wisdom and connection. In China and many Asian countries, it is seen as the color of happiness, glory, harmony and wisdom.
History, art, and fashion
Yellow, in the form of yellow ochre pigment made from clay, was one of the first colors used in prehistoric cave art. The cave of Lascaux has an image of a horse colored with yellow estimated to be 17,300 years old.
In Ancient Egypt, yellow was associated with gold, which was considered to be imperishable, eternal and indestructible. The skin and bones of the gods were believed to be made of gold. The Egyptians used yellow extensively in tomb paintings; they usually used either yellow ochre or the brilliant orpiment, though it was made of arsenic and was highly toxic. A small paintbox with orpiment pigment was found in the tomb of King Tutankhamun. Men were always shown with brown faces, women with yellow ochre or gold faces.
The ancient Romans used yellow in their paintings to represent gold and also in skin tones. It is found frequently in the murals of Pompeii.
During the Post-Classical period, yellow became firmly established as the color of Judas Iscariot, the disciple who betrayed Jesus Christ, even though the Bible never describes his clothing. From this connection, yellow also took on associations with envy, jealousy and duplicity.
The tradition started in the Renaissance of marking non-Christian outsiders, such as Jews, with the color yellow. In 16th century Spain, those accused of heresy and who refused to renounce their views were compelled to come before the Spanish Inquisition dressed in a yellow cape.
The color yellow has been historically associated with moneylenders and finance. The National Pawnbrokers Association’s logo depicts three golden spheres hanging from a bar, referencing the three bags of gold that the patron saint of pawnbroking, St. Nicholas, holds in his hands. Additionally, the symbol of three golden orbs is found in the coat of arms of the House of Medici, a famous fifteenth century Italian dynasty of bankers and lenders.
18th and 19th centuries
The 18th and 19th century saw the discovery and manufacture of synthetic pigments and dyes, which quickly replaced the traditional yellows made from arsenic, cow urine, and other substances.
Circa 1776, Jean-Honoré Fragonard painted A Young Girl Reading. She is dressed in a bright saffron yellow dress. This painting is “considered by many critics to be among Fragonard’s most appealing and masterly”.
The 19th-century British painter J.M.W. Turner was one of the first in that century to use yellow to create moods and emotions, the way romantic composers were using music. His painting Rain, Steam, and Speed – the Great Central Railway was dominated by glowing yellow clouds.
Georges Seurat used the new synthetic colors in his experimental paintings composed of tiny points of primary colors, particularly in his famous Sunday Afternoon on the Isle de la Grand jatte (1884–86). He did not know that the new synthetic yellow pigment, zinc yellow or zinc chromate, which he used in the light green lawns, was highly unstable and would quickly turn brown.
The painter Vincent van Gogh was a particular admirer of the color yellow, the color of sunshine. Writing to his sister from the south of France in 1888, he wrote, “Now we are having beautiful warm, windless weather that is very beneficial to me. The sun, a light that for lack of a better word I can only call yellow, bright sulfur yellow, pale lemon gold. How beautiful yellow is!” In Arles, Van Gogh painted sunflowers inside a small house he rented at 2 Place Lamartine, a house painted with a color that Van Gogh described as “buttery yellow.” Van Gogh was one of the first artists to use commercially manufactured paints, rather than paints he made himself. He used the traditional yellow ochre, but also chrome yellow, first made in 1809, and cadmium yellow, first made in 1820.
At the end of the 19th century, in 1895, a new popular art form began to appear in New York newspapers; the color comic strip. It took advantage of a new color printing process, which used color separation and three different colors of ink; magenta, cyan, and yellow, plus black, to create all the colors on the page. One of the first characters in the new comic strips was a humorous boy of the New York streets named Mickey Dugen, more commonly known as the Yellow Kid, from the yellow nightshirt he wore. He gave his name (and color) to the whole genre of popular, sensational journalism, which became known as “yellow journalism”.
20th and 21st centuries
In the 20th century, yellow was revived as a symbol of exclusion, as it had been in the Middle Ages and Renaissance. Jews in Nazi Germany and German-occupied countries were required to sew yellow triangles with the star of David onto their clothing.
In the 20th century, modernist painters reduced painting to its simplest colors and geometric shapes. The Dutch modernist painter Piet Mondrian made a series of paintings which consisted of a pure white canvas with a grid of vertical and horizontal black lines and rectangles of yellow, red, and blue.
Yellow was particularly valued in the 20th century because of its high visibility. Because of its ability to be seen well from greater distances and at high speeds, yellow makes for the ideal color to be viewed from moving automobiles. It often replaced red as the color of fire trucks and other emergency vehicles, and was popular in neon signs, especially in Las Vegas and in China, where yellow was the most esteemed color.
In the 1960s, Pickett Brand developed the “Eye Saver Yellow” slide rule, which was produced with a specific yellow color (Angstrom 5600) that reflects long-wavelength rays and promotes optimum eye-ease to help prevent eyestrain and improve visual accuracy.
The 21st century saw the use of unusual materials and technologies to create new ways of experiencing the color yellow. One example was The weather project, by Danish-Icelandic artist Olafur Eliasson, which was installed in the open space of the Turbine Hall of London’s Tate Modern in 2003.
Eliasson used humidifiers to create a fine mist in the air via a mixture of sugar and water, as well as a semi-circular disc made up of hundreds of monochromatic lamps which radiated yellow light. The ceiling of the hall was covered with a huge mirror, in which visitors could see themselves as tiny black shadows against a mass of light.
