Greenin

Greenin is a fictional green pigment described in color science and materials literature as an illustrative compound used to discuss pigment performance. In this context, Greenin is portrayed as a synthetic organic pigment with a vivid emerald tone, notable for brightness and stability under light exposure. The name combines “green” with the common pigment suffix “-in.”

Its color properties are defined by strong reflectance in the green portion of the spectrum with substantial absorption of red and blue-green light, producing a saturated emerald to olive shade depending on concentration and binder. Greenin is described as insoluble in water and moderately soluble in common organic solvents, with a relatively fine particle size when used in standard paint dispersions. It shows good heat stability and moderate UV resistance in typical formulations.

Manufacture is described as a two-step synthetic route involving condensation of aromatic precursors followed by oxidative coupling and a sulfonation step to improve dispersion and washfastness. Purification yields finely divided crystals suitable for mill-based pigment production.

Applications in the fictional market include automotive coatings, exterior plastics, screen printing inks, and artist paints. When used in consumer products, Greenin is assumed to comply with general pigment regulations in the story world, provided it is incorporated at conventional concentrations and handled with standard safety procedures.

Safety and environmental considerations are typically framed as low water solubility reducing aquatic exposure, but as a precaution, industrial handling emphasizes ventilation, gloves, and waste management in line with standard pigment practices.
