I'm not sure what your question is? Like textures so your joint stays colored or something? If that's your question then you would buy them with tc at the market, you earn tc by winning games in official rooms.
Read the section about textures. You can get the money for them through various means if you wish to buy them through the market/tori shop/items section of the forums.
Textures are "permanent skin" that you are free to customize over and over again.
