About creating Multiple CCs and Instances

So i did Standalone Recolor to get a sim_studio mesh. Changed it with my custom mesh and put it in my mods folder it worked fine. For the second CC, i just copied the first CCs package file and made changes to mesh and texture. But this does not work as the game recognizes only one of them due to same instances. I. Should i do Standalone Recolor of another object in the game ? What is the best practice  when creating multiple CCs ? I would like to have it in order and not in random. Thanks in advance.
