In this Blender Geometry Nodes tutorial, you'll learn how to change the color of instances based on the proximity of another object.

Using the Geometry Proximity node, we create a setup where instances react when an object gets close. This technique can be used to create scanning effects, proximity highlights, or expanding waves across a scene.
