This month at The Conservation Center, we were inspired by the marvellous hues of autumn, as our hometown of Chicago is being swiftly engulfed by red, orange, and yellow leaves. So we decided to revive our Pigment of the Month segment. For the month of October, we chose a beautiful and historically fascinating yellow pigment- perfect for fall- with a very interesting story behind it.
Indian Yellow is a vivid orange-yellow pigment that originates from India in the 15th century and was mostly used there during the Mughal period. It was introduced to European artists shortly thereafter, where it was used until it became commercially unavailable in the early 20th century. This pigment was a popular choice among frescoists, oil painters, and watercolorists, although it was said to have an unpleasant odour.
This odor may stem from the alleged original source of the pigment— cow urine. Story goes that the cattle responsible for Indian Yellow were only fed water and mango leaves, ingredients that supposedly made their urine (and thereby the pigment) especially luminescent.
