Vary a 3D line color based on the geometry z-value or slope?

[IanLadd_Tourmaline]

I have a 3D pipeline that I would like to create a color gradient symbology style that changes color based on the z-value in the feature's geometry and also another one where it changes based on the slope angle between two of the vertices?

How would I go about doing so? Something like this (Viewed on the side)

Found a solution, but it's a bit difficult, was hoping for something a little more simple. https://community.esri.com/t5/arcgis-pro-questions/elevation-symbology-with-vector-files/td-p/126046...
