What are named attributes?
Named attributes can be thought of as variables inside your Blender project.
Attributes can be used in many parts of Blender. For example, attributes are used in weight painting, the positions of points, and vertex groups. A lot of things are controlled using attributes – for example, the Geometry Node editor, the Material nodes editor, and some entries in the Physics simulator in Blender. In this exercise, we will be using them to link the Geometry Node editor and the Material Nodes editor.
The node that we’ll be using to store these named attributes is called the Store Named Attribute node.
The Store Named Attribute node will store the result of a value on Geometry in an attribute name. On which geometry this information is stored is dependent on the Geometry input socket.

The Geometry output of this node will just output the geometry with the named attribute...
