Yellow<\/a> is the color situated between Green<\/a> and Orange<\/a> on the Visible Spectrum<\/a>. It is characterized by light with a dominant wavelength of approximately 570–590 nanometers. In the RYB Color Model<\/a>, traditionally used in art and design, yellow is a Primary Color<\/a>. According to Britannica<\/a>, it is the most luminous of all the colors of the spectrum.<\/p> The use of yellow in human expression dates back thousands of years. Yellow Ochre<\/a>, a pigment made from clay, was one of the first colors used in Cave Painting<\/a>. In Ancient Egypt<\/a>, the color was synonymous with Gold<\/a>, which was believed to be the flesh of the gods. During the Renaissance<\/a>, yellow was often used to signify betrayal, but it also represented enlightenment. The artist Vincent van Gogh<\/a> famously used vibrant shades of yellow to convey emotion and vitality, most notably in his series of Sunflowers<\/a>.<\/p> In the natural world, yellow serves various biological functions. Many flowers use yellow to attract Bees<\/a> and other pollinators. Animals may use yellow as a warning signal, a phenomenon known as Aposematism<\/a>. In the CMYK Color Model<\/a> 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<\/a>, which provide the hue for Lemons<\/a>, Corn<\/a>, and Autumn Leaves<\/a>.
