Hello
here is a solution using Grasshopper. As I understand you want to apply displacement and depending of the displacement colorize your mesh. I have done a mesh isoplitting which could be useful.
I propose you a script that is doing a real egg shape as a surface. This surface is remeshed and some displament is added as a proportion on the height with a sinus. But you could imagine whatever function you want.
and then iso splitting, enter a mesh, a value for each point and an iso value and you will get 2 meshes. That normally could be joined without hole.
