Dayflower/Turmeric: Ukiyo-e colorant
Dayflower + Turmeric: Green is achieved by mixing or overprinting a blue and a yellow colorant. Dayflower and turmeric was used to create a green which is commonly seen in early prints of two to three colors. The dayflower+turmeric mixture was later supplanted by indigo+orpiment which is the most commonly seen green.

Analysis
Excitation Emission Matrix (EEM) spectroscopy can easily identify turmeric due to its high fluorescence and clear, consistent pattern. Another yellow colorant thought to have been traditionally used, Japanese yellow wood or kihada also fluoresces very brightly but they give very distinctive EEM patterns, making it easy to differentiate between the two. Yellow wood has not been detected so far.
