📜 Origin & History

Deep Green appeared widely in Victorian-era wallpapers and interior textiles; because its formula often contained arsenic, it sparked public health discussions of the time, indirectly promoting research into safe pigments.

In the early 20th century, Deep Green became the security under-color for many national banknotes because early photography had difficulty reproducing this color, establishing the visual link of 'green equals money'.

In the digital age, Deep Green was one of the few colors that could be displayed relatively purely on early CRT monitors, hence its widespread use in early computer games (like Snake).

Today, American tattoo culture considers Deep Green a classic among traditional tattoo inks; because it lasts relatively long on skin, it is used as a standard color for shading and foliage.
