Why was green chosen for American paper currency?

Senior Moments

The green ink that has been used since 1862 to print U.S. banknotes was invented in 1857 by Thomas Sterry Hunt while he was a professor at McGill University in Montreal. Hunt was the staff analytical chemist of the Canadian Geological Survey and it was during his time in this position that he started becoming familiar with chromium-containing minerals. For the banknote ink he proposed the use of chromium sesquioxide, also known as chromium trioxide. The green ink is the reason why so many counterfeiters are unsuccessful at reproducing U.S. currency. This green ink also cannot be destroyed by acid, base or any other agent. The green ink has another very important characteristic: it cannot be copied by photography. http://www.chem-inst-can.org/ncw/articles/egreenink.html Jan 04 02, 11:04 PM
