The redesign of the $20 bill was supposed to be unveiled to the public this month, but we won’t be seeing it until May. The new bill will actually make use of colored inks, something the U.S. has been reluctant to adopt despite the prevalent use of colorful bills in other countries. However, the color additions will likely be minimal, keeping us in the green. It would be neat in the future to have to explain to our grandkids why people use the term “greenbacks” to refer to cash though. Of course, by then there may not be any cash to speak off.
