How to Save 3D picture in color?

I am trying to save a mountain visualization as it appears in gCLUTO interface that is keeping all the colors. I have used .gif, and .jpeg extentions, but when I open the file, the picture does not have any colors - everything is in grey scale. When I am saving, I use the option print to file, since the program gives me an error when I press save for the 3D picture. Could you, please, suggest what could be done? I would like to include these pictures in my conference paper.

Thank you
