[vtkusers] how can I change the color when using surface rendering

[zhq]

Dear all :
      I don't know how to change the color when using surface rendering 
   
      Firstly , I use dicom read to get the data , and get the surface
through marching cube . then display the 

data with mapper , actor , renderer ...  

     The color of result is blue , I want to change the color to gold . 
     
     What I have tried is :

     actor->GetProperty()->SetColor(0,1,0);

     but nothing happened , the color is still blue .

     What can I do ?

     Thanks in advance !
