Editing Yellow (section)

==== 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.<ref name="Yellowtown" /> 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.<ref name="Yellowtown" />

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.<ref name="newyorker.com">Cynthia Zarin (13 November 2006), [http://www.newyorker.com/archive/2006/11/13/061113fa_fact_zarin#ixzz1FQvk1dMc Seeing Things.
