Chrome yellow
October 6th, 2024

Chrome yellow is a bright, warm yellow pigment that has been used in art, fashion, and industry. It is the premier orange pigment for many applications.[2]

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.[5] According to Gettens, especially when mixed with organic colors, it can take on a green tone. This effect is attributed to reduction of some chromate to chromium(III) oxide.[6] 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.[7] Artists began using cadmium yellow instead of chrome yellow when they became aware of chrome yellow's instability.[8]: 190
