While exploring Houdini, I learned how to use VEX to imitate the behavior of the Rest and Color geometry nodes. The Rest node simply adds a new vector to the geometry spreadsheet called 'rest' which copies over the position values (P) for each point. The Color SOP adds a "color vector" called "Cd" to the geometry spreadsheet with the RGB values you select. I demonstrate this and also show how you can name the color data anything you want, and then copy it over to a geometry using the Attribute Copy node.
Stay tuned! Bonus features for this video are under development...
If you want to make Hollywood quality visual effects (VFX), then you will want to learn Houdini. Houdini is a procedural system from Side FX Software that empowers you to create everything from realistic terrains, water effects, pyro simulations, and realistic assets for both film production and game development.
