Topographic slope analysis

How can I do this (a topographic slope analysis) with land design or with grasshopper?

See attached.

Blending Vertices Colors from classic LimeGreen (i.e. flat like Earth) to classic Red (i.e. flat like Everest).

BTW: Obviously the smoother the Mesh … the better the visual result. Meaning: avoid inputing bananas.

Here’s a basic solution operating on vertex normals using native components/no scripting:

Hi Anders
Coming back to this after a long time, but I was wondering if you can unpack the ReMap and how I would specify grades for that? (or refer me to how I can unpack it).
Also, how I might then divide the mesh to select the areas of certain grades to them use as geometries (I know this is a cheeky bonus question I am adking)
Thanks man
