When you create a point cloud, every point has the same color and style, as every point uses the same THREE.PointCloudMaterial object. There is, however, a way to add color to the individual points.
There is no need for any additional steps to run this recipe. We'll create a custom geometry, just like we did in the Creating a point cloud from scratch recipe, and this time, we color each individual point. The result of this recipe can be seen by opening 06.03-color-individual-points-in-point-system.html in your browser. You will see something similar to the following screenshot:
As you can see, we've colored the individual points in various shades of red.
