Indigo + Orpiment: Green is achieved by mixing or overprinting a blue and a yellow colorant. The dominant formulation for green after the introduction of full-color printing after 1765 is a mixture of indigo and orpiment. By altering the proportions of each, a wide variation of greens could be obtained. The preference for this formulation of green might be due to the relative stability of both indigo and orpiment to moisture. However like most of the colorants used for woodblock printing during the Edo period both will fade upon prolonged exposure to light.

Analysis

Fiber optic reflectance spectroscopy (FORS) is used to identify indigo and X-ray fluorescence analysis (XRF) is used to detect arsenic, which is an indication for the presence of orpiment (As2S3).
