You can get by with using the object pattern to color the
edges differently.
Or you can do this with find-edges as a post-process with
a paint program for more complicated scenes.

#include "shapes.inc"

#macro outlined_box(a b os c1 c2)
   box{a,b pigment{object{Wire_Box_Union(a-os,b+os,os) c1 c2}}}
#end

union {
   outlined_box(<-0.5,-0.5,-0.5>,<0.5,0.5,0.5>,0.1,Red,Green)
   rotate 45*y
   rotate 45*x
}
