The Color Corps of the Knights of Columbus are the uniformed members of the Fourth Degree. They are the most visible arm of the Knights of Columbus and are the ones most noticeable at church and public functions, parades, etc.

The Color Corps  actually is made up  of two parts: the Honor Guard and the Color Guard. Honor Guardsmen takes part in the civic and religious functions and are those members that have mastered the Manual of the Sword. While the Color Guard also carries out those duties, the Color Guard is responsible for caring and displaying the flags in parades and ceremonies. The Color Guard is drawn from members of the Honor Guard.

Membership in the Color Corps is voluntary and is open to any member in good standing of the Fourth Degree. All members of the Color Guard must be trained regularly and certified before they can take part in any functions.

The Corps basically follows a naval theme with rank and insignias. Note the chapeaux (which are never called hats) are similar to the old naval uniforms. Cape colors are an indication of rank.
