Hello again,

You can read this section of the manual: 
https://doc.cgal.org/latest/Surface_mesh/index.html#title7

Basically, you have to create 3 simplex properties with 
`mesh.add_property_map<vertex_descriptor, unsigned char>("v:red")` and 
so on, and these will be written by `CGAL::write_ply` (it should also 
work if you prefer to color faces instead of vertices, just use a face 
property in that case).

I hope this helps.

Best,
