Yes, you can bleach an unbleached Judo gi.
However, it is not going to come out right. They never do. An unbleached gi is generally used as a "practice" gi or training gi. It also get a funny feel to to it after you bleach it. I highly recommend to keep it unbleached.
If you are trying to bleach it blue, for a competition gi, I also advise not to do it. You must be within a very specific color range of blue for it to be legal (pantone color 265 for us judo geeks).
Judo gi
A Judo Gi. The Gi in Japanese is translated into uniform. There are different types of uniforms. White and Blue, competition one and non-competition. Normally you will wear your non-competition uniform in your Dojo (the hall where you train with your instructors) And you'll wear your thick and heavy Gi to competitions. Also, it's very useful to own both white and blue uniforms. Because at competition you may be asked to switch colours. I personally use my blue Gi for competitions and my white Gi when I'm training. Hope this helps :)
For judo it means have a GI
all purpose flour has bleach in it, therefore when you eat anything made with all purpose flour you are eating bleach.
Grey is not a color of judo . White and blue colored gi(dress),and belt color may different .

Judo training uniform is called Judogi or you can just called Gi.
Answer: Unbleached fabric has a light beige or natural off-white color.I think its is called Grey
Judokas wear a Judo Gi. It is somewhat like those white outfits you see Karate-kas wearing, or most other martial artests.
I wouldn't. Karate gi's tend to be lighter weight then a judo gi. It would likely be ripped to shreds within a class or two. The Judo gi is heavy cotton and is usually quilted with reinforced seams for a lot of grappling.
they wear a gi which is common in guju ryu karate or a white shirt with sweat pants or judo pants
A decent mat is usually enough. Most judoka also train in specialized uniforms called "judo gi" which are tough enough to stand up to repeated tugs, yanks, and throws, but with a little creativity you can train in t-shirts and sweatpants.
