Saint Patrick Blue: He Wasn't Always Green
On Saint Patrick's Day, we wear green clothing, drink green beer, and watch as some prominent rivers are dyed green. The verdant color is, after all, the color of the Emerald Isle, so it must be associated with Saint Patrick, right? Wrong. Saint Patrick was originally associated with the color blue, not green, to the point that there's an entire shade named "Saint Patrick blue." So why do we celebrate Saint Patrick's Day with the wearing o' the green?
