Wei,

 

Actually the representations from your example look more like transparent surface and stick representations of the ligand.  This can be accomplished a few ways, but if you want independent coloring schemes for each representation, then you will have to do as Jurgen suggested....creating two objects, one for transparent surface and the other in stick.  below are a few links that might help....

Good luck!

 

 

 

 

Cheers,
