Hi Ian,
Check out "Surface Capping" (under Tools... Depiction).  When you  
turn on "cap surfaces" it hides the inside of the clipped surface  
with a solid plane so it looks like you are slicing a block of marble  
or cheese rather than a thin shell.  There are various options for  
the display and color of the "cap."

There is no way to make the inside of a surface a different color  
than the outside, but I am hoping this capping option will meet your  
needs.  If you are working with contour surfaces from Multiscale  
Models or Volume Viewer, there are some lighting options that affect  
the inside/outside appearance (if so, and you would like more details  
on that, let me know), but usually capping is the way to go.
