[AndersDeleuran]

Here’s a basic example of coloring mesh vertices by their Z value using Grasshopper:

You can open the file directly with Rhino or drag-and-drop it.

If you’re looking to color the mesh faces instead, you can do something like this (using Python):

Question about mesh coloring

There’s a couple of approaches to this over here: I think you probably could implement this logic (i.e. unweld the mesh and color its faces) with Grasshopper components. But it’s quite simple with code, in that one can implement the SetColor method directly on a face now (i.e. since Rhino 6): [2021-03-08 09_07_53-Rhinoceros 6 Commercial - Perspective] 210308_ColorMeshFaces_00.gh (9.5 KB)
