 The Browns are the only National Football League team without a helmet logo.The logoless helmet serves as the Browns' official logo.The organization has used several promotional logos throughout the years; players' numbers were painted on the helmets from 1957 to 1960; and an unused "CB" logo was created in 1965, But for much of their history, the Browns' helmets have been an unadorned burnt orange color with a top stripe of dark brown (officially called "seal brown") divided by a white stripe.
