In 1984, the helmet's shell color was changed from white to red, primarily to help Bills quarterback Joe Ferguson distinguish them more readily from three of their division rivals at that time, the Baltimore Colts, the Miami Dolphins, and the New England Patriots, who all also wore white helmets at that point. Ferguson said "Everyone we played had white helmets at that time. Our new head coach Kay Stephenson just wanted to get more of a contrast on the field that may help spot a receiver down the field." (The Patriots have worn silver helmets since 1993, the Colts have since been realigned to the AFC South, and in 2019 the New York Jets have since switched back to green-colored helmets, after playing 20 years with white ones.)
