Winsor Emerald is a bright clean opaque emerald colour. First documented in 1822, it originally contained arsenic, and is said to have killed Napoleon as his wallpaper in St Helens was emerald green. Winsor & Newton have created a non-toxic version closely matching the original colour.

溫莎祖母綠(Winsor Emerald)是一種明亮乾淨的不透明祖母綠(Emerald)顏色。 最早記載於 1822 年，它最初含有砷，據說殺死了拿破崙，因為他在聖海倫斯的牆紙是翠綠色的。 Winsor & Newton 創造了與原始顏色非常匹配的無毒版本。
