public ColorLevelCommandData Blue { get; set; }

@property (nonatomic, strong) LTColorLevelCommandData *blue;

public ColorLevelCommandData getBlue(); 
public void setBlue( 
   ColorLevelCommandData colorLevelCommandData 
);

public: 
property ColorLevelCommandData^ Blue { 
   ColorLevelCommandData^ get(); 
   void set (    ColorLevelCommandData^ ); 
}

Blue # get and set (ColorLevelCommand)
