About the color Emerald

Named after the gemstone

Emerald takes its name from the green gem, which is also the birthstone for May. Maerz and Paul's A Dictionary of Color of 1930 dates the first use of emerald as a color name in English to 1598.

Two codes for one name

This site uses #50C878, a soft medium green. Wikipedia's list of colors credits that code to Maerz and Paul, but the claim is marked as needing a citation. The Wikipedia article on shades of green now shows emerald from the same book as a much brighter #00FF60. So treat #50C878 as a common web version of emerald, not an exact copy of the book.

On this site, Paris green has the same code. For a deeper, bluer gem green, look at jade.

A green that poisoned people

In 1814 two paint makers in Schweinfurt, Germany, made a bright new green pigment. It was made with copper and arsenic. People called it emerald green, Schweinfurt green or Paris green. Victorian women wore it in dresses, and florists used it on fake flowers. It was also printed on cheap wallpaper, where the dust made people sick and caused deaths. Later it was sold to kill insects and rats.

Color of the year

Pantone named its shade 17-5641 Emerald the Color of the Year for 2013. It took over from Tangerine Tango, the pick for 2012. More greens like this one are on the shades of green page.
