can you color the belts black if they are another color and what can you us to do this

Many people have used RIT dye on their belts to change colors. The only problem I see is you will also dye the manufacture/date code tag as well.
Follow the RIT dye directions.

I dyed mine with rit, and after washing them, the tag was white again, and the belts are still black (started out gold).
