The Steelers logo is based on the Steelmark logo belonging to the American Iron and Steel Institute (AISI).The logo's meaning was extended to include the three materials used to produce steel: yellow for coal, orange for ore and blue for steel scrap.
Pittsburgh is known for steel so they named them after the steel and their logo is the steel symbol only in different colors.
The Steelers logo has three colored astroids, a hypocycloid with four cusps, (yellow, red and blue) and the name Steelers written in black to the left of them. It is encased in a gray ringed, circular white background.
