Bandanas

Bandanas are a recurring and iconic item in the TMNT franchise, appearing in essentially every incarnation to some extent, and the sight of the standard TMNT bandana in other contexts is still ubiquitously identified with them.

The regular bandana seen in the franchise is actually a hachimaki (鉢巻), a traditional headband popular throughout Japan, with holes cut out for the eyes. Other characters than the Ninja Turtles also wear these bandanas, usually in imitation of the Turtles, or a standard hachimaki around the forehead. Still others (as well as sometimes the Turtles themselves) wear full headscarf-style bandanas (sometimes with eyeholes cut out).

The colors of the bandanas are as iconic as the bandanas themselves. While the original wore red bandanas exclusively in color images of them, the blue, orange, red, and purple ones starting with  have become immersed in pop-culture.
