Silver and blue signifies Peace and Sincerity and Truth and Loyalty. On its shield at its center, the IUF insignia, the heart of every Undefiable guarded by three daggers symbolizing many aspects of IUF traditions and beliefs: the Triumvirate Principles (3 Legends, 3 Brothers, 3 Founders), the Equilateral Triangle, the Holy Trinity.

On its crest a mighty sword from a warrior, guarding the tenets of this brotherhood, benevolent and humble.

IUF, always a shinning example of courage in integrity as a Protest Fraternity.

The shield bears the two-headed eagle signifying two equal and conjoining forces: the fraternity and the sorority, and the Interminably Undefiable insignia.

On its crest, the Wings of an Eagle in the left and a Lion in the right. The wings signify a noble nature and integrity of a brother. One who is high-spirited, ingenious, quick-witted, and judicious, with real magnanimity and strength of mind.

The Lion symbolizes dauntless courage. Not the courage associated with war and blood, and not like the superficial impression this coat of arms gives (mysterious and strange).

This Coat represents the generally prejudiced fraternity life. It is our will and duty to have courage to defend its principles to those who misdjudge our genuine hearts. Observe its colors. Red, always associated with "gore", and Gold with "power and arrogance." Instead, IUF brings to life Red as the color for a "true warrior for integrity" and Gold for "generosity and elevation of mind."
