I'm not sure what it is that you're asking about colors. Here is the
key part of the documenation on the faces object:

You can append additional vertices to an existing faces object with
one of the following four forms (assuming the object is named f):

f.append(pos=(x,y,z))
f.append(pos=(x,y,z), normal=(nx,ny,nz))
f.append(pos=(x,y,z), normal=(nx,ny,nz), color=(r,g,b))
f.append(pos=(x,y,z), normal=(nx,ny,nz),
     red=r, green=g, blue=b)

Another convenient way to construct a faces object is to create a list
or numpy array of positions, then create the faces object with the pos
attribute set to the list or array. Then use make_normals(),
make_twosided(), and smooth() to complete the task.
