Black and white armor evolved as an economical replacement for white armor with the added benefits of an aesthetically pleasing composition which required less maintenance. The black areas were finished with the hammer only and coated with Brunswick black. The embossed patterns provided additional rigidity as well as a palate for the armorers artistry often with a striking result. For helmets, the fleur-de-lis was among the most popular motifs as it provided a pleasing and recognizable image with the strengthening relief borders well distributed on the skull for maximum benefit. This example is typical of those worn by guard units including the Amsterdam Town Guard.
