About Paris Green Color

Paris green was a brilliant nineteenth-century copper arsenic color used in paint, wallpaper, printed books, and other decorative goods—and later as an insecticide. The National Park Service documents an unusually concrete architectural example: store ledgers and surviving paint helped establish that White Haven, Ulysses S. Grant’s Missouri home, was painted Paris green in 1874 and returned to that Victorian-era appearance during restoration.

A screen swatch can borrow the historic color’s startling intensity without carrying its chemistry. Original Paris green contains arsenic and can be hazardous if pigment particles are ingested or inhaled; unidentified historic books, wallpapers, and paint should therefore be treated as materials, not sampled or disturbed for a color experiment. Digitally, the hue is effective as a high-energy accent against ink, cream, or deep violet.

This page documents a digital color and historical context. It is not a material-identification method, handling protocol, restoration formula, or assurance that an object is safe.
