Renaissance and the Baroque

During the Renaissance and the Baroque, grey began to play an important role in fashion and art. Black became the most popular color of the nobility, particularly in Italy, France, and Spain, and grey and white were harmonious with it. Grey was also frequently used for the drawing of oil paintings, a technique called ''

Eighteenth and nineteenth centuries

Grey became a highly fashionable color in the 18th century, both for women's dresses and for men's waistcoats and coats. It looked particularly luminous coloring the silk and satin fabrics worn by the nobility and wealthy. Women's fashion in the 19th century was dominated by Paris, while men's fashion was set by London. The grey business suit appeared in the mid-19th century in London; light grey in summer, dark grey in winter; replacing the more colorful palette of men's clothing early in the century. The clothing of women working in the factories and workshops of Paris in the 19th century was usually grey. This gave them the name of ''grisettes''. "''Gris''" or grey also meant drunk, and the name "''grisette''" was also given to the lower class of Parisian prostitutes. Grey also became a common color for military uniforms; in an age of rifles with longer range, soldiers in grey were less visible as targets than those in blue or red. Grey was the color of the uniforms of the

In the sciences, nature, and technology


Storm clouds

The whiteness or darkness of clouds is a function of their depth. Small, fluffy white clouds in summer look white because the sunlight is being scattered by the tiny water droplets they contain, and that white light comes to the viewer's eye. However, as clouds become larger and thicker, the white light cannot penetrate through the cloud, and is reflected off the top. Clouds look darkest grey during thunderstorms, when they can be as much as 20,000 to 30,000 feet high. Stratiform clouds are a layer of clouds that covers the entire sky, and which have a depth of between a few hundred to a few thousand feet thick. The thicker the clouds, the darker they appear from below, because little of the sunlight is able to pass through. From above, in an airplane, the same clouds look perfectly white, but from the ground the sky looks gloomy and grey.


The greying of hair

and which makes up our hair, skin, and nails. As long as the melanocytes continue injecting melanin into the hair cells, the hair retains its original color. At a certain age, however, which varies from person to person, the amount of melanin injected is reduced and eventually stops. The hair, without pigment, turns grey and eventually white. The reason for this decline of production of melanocytes is uncertain. In the February 2005 issue of ''Science'', a team of Harvard scientists suggested that the cause was the failure of the melanocyte stem cells to maintain the production of the essential pigments, due to age or genetic factors, after a certain period of time. For some people, the breakdown comes in their twenties; for others, many years later. According to the site of the magazine ''Scientific American'', "Generally speaking, among Caucasians 50 percent are 50 percent grey by age 50." Adult male gorillas also develop silver hair, but only on their backs – see Physical characteristics of gorillas.

An example of a political party using grey as a color are the German Grey Panthers. The term "grey power" or "the grey vote" is sometimes used to describe the influence of older voters as a voting bloc. In the United States, older people are more likely to vote, and usually vote to protect certain social benefits, such as
