TCU Horned Frogs

TCU Horned Frogs is the athletic identity of Texas Christian University in Fort Worth, Texas, built around the arched TCU wordmark as its primary athletics logo with two horned frog depictions as secondary marks. In 2012 the department debuted a deeper purple developed with Nike.

TCU Horned Frogs is the athletic identity of Texas Christian University in Fort Worth, Texas. The university’s visual identity centers on the arched “TCU” wordmark, which serves as the primary athletics logo, alongside two official horned frog depictions used as secondary identifiers.

Design and History

The arched TCU logo has served as the university’s emblem for more than three decades, according to TCU’s official brand site.[1] In May 2012, TCU Athletics announced it would use just the arched TCU as its primary athletics logo and mark, while keeping the frog as part of the brand. The department also debuted a deeper shade of purple that fall, developed over more than a year in conjunction with Nike, after fans said uniforms and helmets appeared bluish on television.[2]

Before the arched TCU, the university used the “Flying T” mark. Marshall K. Harris, a TCU football student-athlete, designed the Flying T for one of his art classes in 1977. After sharing it with coaches, the school approached him about using it on football helmets and uniforms, and it saw widespread adoption across all TCU athletics into the early 1990s.[3] The Flying T was used by the university from the late 1970s until 1994 in all sports.[3] In 2022, TCU announced a limited-time return of the retired Flying T mark to retail merchandise as part of the university’s 150th anniversary celebration in 2023.[4]

The horned frog has been associated with TCU since 1897, when students and school officials adopted “Horned Frog” as the title for the student yearbook, and the lizard was soon embraced as the school mascot.[5] The horned frog was included on TCU’s first seal in 1915 and was widely used to represent the school after World War II.[6]

Meaning and Symbolism

TCU’s official brand site describes horned frogs as “spiked, heavily armored and fiercely territorial.” The Texas horned lizard is the state reptile of Texas. Horned lizards are affectionately known as horned frogs, but are not amphibious creatures; the nickname comes from the lizard’s rounded body and blunt snout, which give it a decidedly froglike appearance.[7]

The university uses two special horned frog depictions as additional visual identifiers: the signature University Frog and the Athletic Frog. The University Frog may be used on all university publications, with or without the arched TCU logo. The Athletic Frog is reserved for athletics and can be used as a spirit mark on non-athletics publications geared toward school pride with approval of the associate athletics director of marketing. The Athletic Frog cannot appear with the arched logo; the two can only appear together on football helmets.[7]

SuperFrog is the official mascot of Texas Christian University. The original costumed mascot, “Addie the Fighting Frog,” debuted at the opening game of the 1949 football season, named after Addison Clark Jr., who promoted intercollegiate athletics during the early years of the university.[5] In 1979, TCU athletic promotions director John Grace created SuperFrog, wanting a mascot “which people could laugh with, instead of laughing at.”[5]

Typography and Design

TCU’s official brand guidelines specify that all TCU logos must adhere to the width of the character C in the arched application of “TCU.” All TCU collateral must include the arched TCU logo no smaller than half an inch, and the logo is not to be used as a word.[8]

The official color is Horned Frog Purple, specified as PMS 268 C, with CMYK 79, 100, 0, 20 and HEX #4D1979.[9] TCU’s school colors are purple and white, but purple has long been the strongest color for TCU. The predominant color should be purple PMS 268, and the correct TCU purple for website development is #4d1979.[10] The primary palette also includes Horned Frog Grey (PMS 429 C), Black and White. Red is reserved for athletics only, in limited use as an accent color.[9]

When presenting either frog, the color purple should be used, but certain approved color variations, such as gray or black, may be used. When printing with PMS colors, the color purple must be PMS 268.[7]
