Conventional taekwondo uniforms are colored white since it
represents the clarity of vision and neutrality of the practitioner. Some karate
institutions and schools also use other colors like red, black, blue or brown.
The color of the karate uniform is usually based on the school or tradition that
you have chosen. It is highly disrespectful to a school where you practice
karate to wear a different colored karate uniform.

Some  schools also require or advocate the wearing of mouth guards, albeit this is not  a traditional way of practicing karate. Some additional gear also includes knee  or elbow protectors and embroidery. This is usually done by parents who want to  protect their kids from getting serious physical injuries when practicing  karate. Some schools allow their students and practitioners to place their  schools patches on their karate uniforms as a sign of pride or of publicity to  allow more students to join their practice.
