Logos and uniforms
Logo
The script logo.
The Dallas Cowboys' blue star logo, representative of Texas as "The Lone Star State", is one of the most well-known team logos in professional sports. The blue star originally was a solid shape until a white line and blue border was added in 1964. The logo has remained the same since. Today, the blue star has been extended to not only the Dallas Cowboys, but owner Jerry Jones'
AFL team, the
Dallas Desperados that have a similar logo based on the Cowboys. The blue star also is used on other entries like an imaging facility and storage facility.
Uniforms
The Dallas Cowboys' white home jersey has royal blue (PMS 287 C) solid socks, numbers, lettering, and two stripes on the sleeves outlined in black.
The home pants, according to the Dallas Cowboys official media guide, are a common metallic silver-green color (PMS 8280 C) that help bring out the blue in the uniform. The navy (PMS 289 C) road jerseys (nicknamed the "Stars and Stripes" jersey) have white lettering and numbers with navy pinstripes. A white/gray/white stripe are on each sleeve as well as the collared V-neck, and a Cowboys star logo is placed upon the stripes. A "Cowboys" chest crest is directly under the NFL shield. The away pants are a pearlish metallic-silver color (PMS 8180 C) and like the home pants, enhance the navy in the uniforms. The team uses a serifed font for the lettered player surnames on the jersey nameplates.
