Mayavi Python How to dye each 3D vertex differently

Question

I wrote a script that loads a 3D point cloud in ply format converts it to an np array and then draws the point cloud with mayavi. This process works

But the color of the vertices is not taken into account. There is a function that dye all points the same but I would like to use the colors for each point from the ply file like in meshlab. Thanks in advance best Max
