The Armor-pulling Scene at Wada's Banquet by Utagawa Toyoharu

Orpiment 石黄 (sekiō): An inorganic colorant ground from a soft, yellow mineral composed of Arsenic trisulfide. It produces a brilliant golden yellow color.

Orpiment and turmeric have been the most commonly detected yellows either as single colorants or as a mixture of the two. Orpiment may have been added to increase opacity and create a vibrant rich golden yellow. An impressive number of greens can be produced when it is mixed in varied proportions with indigo. From the 1770s through the 1860s, the dominant green used for printing appears to be a mixture of these two colorants. Orpiment also frequently appears to be overprinted or mixed with safflower to create orange.

For additional information see: Orpiment

Analysis

X-ray fluorescence analysis (XRF) is used to detect arsenic (As) and sulfur (S) (depending on instrument settings). When it is found in an area where a yellow colorant was used such as yellow, orange, and green, it is an indication for the presence of orpiment (As2S3).
