it's all about order ..... in your scene file if you have #include 
"colors.inc" before you have #include "myobject.inc" it will know about the 
colors without having those entries in the .inc file also. if your object 
had just one texture or pigment, you could build you object in the .inc file 
without any mention of color. Back in your scene file (.pov) you could call 
your object like this:  object {MyObject {pigment Green}} since your object 
has more that one pigment/texture i'd make the .inc file a macro that way 
you could call your object like this: MyObject (T_Stone1, Green) or MyObject 
(T_Stone2, Blue)

hope this helps
