On January 15, 2011, the Steelers wore their black home jerseys against the Ravens.
The basic colors are Purple, Black, White, and Metallic Gold. Purple and Black are derived from the natural colors of a Raven (bird). The Gold and White colors are derived from the Official Seal of the State of Maryland. Normally, home game uniforms are Purple Jerseys over White pants; however, on special occasions, the Ravens will wear Purple Jerseys over Black pants for a more intimidating look. Away uniforms are usually either White on White, or White on Black.
