how to control the color of a section in trimesh?

How can I control the color of the section of a trimesh object, as When I do a section and display it the color seems to be missing. for example:

hexagon_with_pores = create_hexagon_with_pores(edge_length, height, pore_radius)
face_colors = np.zeros_like(hexagon_with_pores.faces)
face_colors = [0.7, 0.7, 0.7]
hexagon_with_pores.visual.face_colors = face_colors
scene = trimesh.Scene([hexagon_with_pores])
scene.show()
# Sections
section_top = hexagon_with_pores.section(plane_origin=[0, 0, height/2], plane_normal= 
[0, 0, 1])
section_side = hexagon_with_pores.section(plane_origin=[0, 0, height/2], plane_normal= 
[0, 1, 0])

What do you mean by this?

If you are using some third-party library, then you should show us which one it is, and give a basic explanation of what it is used for, so that we have context for the problem.

What you ask might not be possible. If it is possible, there is a good chance that the library documentation will explain it.
