Money is green in the United States, it is believed, because that color of ink was the most readily available when the paper currency design was introduced in 1929. Prior to then, paper currency mainly used black ink with colored elements, but counterfeiters were able to recreate the colored portions too easily. Another possible reason green ink was chosen was because it is more able to withstand heat and chemical exposure without changing appearance. Green ink might also have been chosen for US money because the color green was viewed as a symbol of strength and stability in the government’s credit.
