Dayflower + Turmeric: Green is achieved by overprinting or mixing a blue and a yellow colorant. Dayflower printed over turmeric was typically used on early prints of two to three colors. On prints the appearance of green produced by overprinting turmeric with dayflower can change upon exposure to moisture or fading. The highly water-soluble dayflower can move towards the back of the paper support to reveal the yellow turmeric. Turmeric is also highly susceptible to fading and in some cases the green produced by the combination of these two colors can appear tan. After the development of full color printing, the dayflower + turmeric mixture was largely supplanted by indigo + orpiment, which became the dominate formulation for green.

Analysis
Fiber optic reflectance spectroscopy (FORS) is used to identify dayflower and Excitation Emission Matrix (EEM) spectroscopy is used to identify turmeric. For more information, please see the individual colorant pages, dayflower and turmeric.
