Depends on the system. Some Kung Fu systems and organizations use "sashes" instead of"belts" and the Gold or Yellow Sash is higher ranking than some that wear a "black sash". However, as far as I know with my 36 years of experience in Martial Arts I have come across no "belted" system where a yellow belt would ever out rank a black belt.
Hope this helps.
Yellow
martial or admiralty law.
bahotae is a yellow belt in the sherdog mixed martial arts forums
yellow
higher
Blue then green then orange then yellow
The higher the karat, the darker the yellow will be.
The Yellow belt after the white belt. It is the 2nd position of martial art skill, and the coloring represents the sunlight warming the seed. The warmth of the sun strengthens the seed and gives it new life, representing a student’s capability to admit the original knowledge from their educator with an open mind.
The answer to that is to have a higher score than Jaden or have a higher score than someone in Ra Yellow if you have already been to Ra Yellow. Same with the advancement to Obelisk Blue. If Bastion is higher than any of the O. Blue dolts, you only have to have a higher test score than one of the dolts.
Yellow is a warm, high energy color. Green is a cool calming color.

Ninjitsu is a martial art that was practiced by Japanese ninjas. However, it does not always employ wearing black and killing, as the stereotype often suggests. There are some Martial Arts schools that teach Ninjitsu. Look in the Yellow Pages and call different schools to see if there is someone in your area. You can go to classes and get better and better.
