Plotting surfaces in different colors

[julienfranz]

I have a .mesh file having 2 arrays (each corresponds to the interior and exterior part of the mesh): e.g,

Now, how do I plot the two surfaces in different colors? Thank you.

It's a bit hard to tell what's going without a code example, but if I wanted to plot two different meshes with two different colors, I'd:

import pyvista
pyvista.set_plot_theme('document')

mesh_a = pyvista.Sphere(center=(1, 0, 0))
mesh_b = pyvista.Cube()

pl = pyvista.Plotter()
pl.add_mesh(mesh_a, color='r', smooth_shading=True)
pl.add_mesh(mesh_b, color='b')
pl.show()
