320:. Studies focusing on the techniques used in Van Gogh's Sunflowers series have revealed how Van Gogh skillfully mixed various shades of chrome yellow to achieve different effects. Chrome yellow has also been used in fashion and textiles, particularly in the 1920s and 1930s. The vibrant color was a popular choice for flapper dresses, hats, and accessories, and was often paired with other bright colors, such as pink and turquoise. 44: 336:, a natural form of lead chromate, when he identified the presence of a new element, chromium. The discovery led to the synthesis of a variety of new pigments, including chrome yellow. Chrome yellow quickly gained popularity among artists and designers for its bright, sunny hue, which was particularly well-suited for use in fashion and textiles. The earliest known use of chrome yellow in a painting is a work by 229: 361: 303: 249:. Owing to its high lead content, the pigment is prone to discoloration over time, particularly in the presence of sulfur compounds. Its low cost had doubtlessly contributed to its continued use as an artists' color even though some subsequently discovered yellow pigments are more permanent. Artists began using 353:, chrome yellow has long been the focus on safety concerns. Its use is highly regulated. Its former use as a food colorant has long been discontinued. The continued wide use of this pigment is attributed to its very low solubility, which suppresses leaching of chromate and lead into biological fluids. The 682:

Chrome yellow is moderately resistant to fading from exposure to light when it is chemically pure. Observations have found that over time though, it begins to darken and suffer discoloration by turning brown. This degradation is seen in some of Van Gogh's pieces. According to Gettens, especially when
332:, a chemical compound that was first synthesized in the early 1800s. The discovery of lead chromate, the primary component of chrome yellow, is credited to the French chemist Louis Nicolas Vauquelin. Vauquelin was studying the mineral 216:. This replacement is possible because sulfate and chromate are isostructural. Since sulfate is colorless, sulfochromates with high values of x are less intensely colored than lead chromate. In some cases, chromate is replaced by 340:

to inhibit contact with gases that can change their color. Cadmium pigments in turn are increasingly replaced with organic pigments such as arylides (Pigment Yellow 65) and isoindoles (PY 110).

Chrome yellow pigments are usually encapsulated by coating with transparent oxides that protect the pigment from environmental factors that would diminish their colorant properties.

The raw pigment precipitates as a fine solid upon mixing lead(II) salts and a source of chromate. Approximately 90,000 tons of chrome yellow are produced annually as of 2001.
