Historical and Cultural Context
The use of yellow in human expression dates back thousands of years. Yellow Ochre, a pigment made from clay, was one of the first colors used in Cave Painting. In Ancient Egypt, the color was synonymous with Gold, which was believed to be the flesh of the gods. During the Renaissance, yellow was often used to signify betrayal, but it also represented enlightenment. The artist Vincent van Gogh famously used vibrant shades of yellow to convey emotion and vitality, most notably in his series of Sunflowers.
Science and Nature
In the natural world, yellow serves various biological functions. Many flowers use yellow to attract Bees and other pollinators. Animals may use yellow as a warning signal, a phenomenon known as Aposematism. In the CMYK Color Model used in color printing, yellow is one of the four primary ink colors. The chemical basis for many yellows in nature is the presence of Carotenoids, which provide the hue for Lemons, Corn, and Autumn Leaves.
