Part of my Geometry did not get any color

This is my geometry and also my graph
What is the problem exactly?

Hi @tatdesign96,

Welcome to the Dynamo Forum.
To avoid this superimposition of preview images :
Right click on the nodes which create the geometry (Sphere.ByCenterPointRadius) prior to the GeometryColor.ByGeometryColor node and disable the preview for them.
