ChromaGun 2: Dye Hard PS5

Welcome to ChromaTec, the universal leading producer of the ChromaGun (patent pending)! Here at ChromaTec, colors are magnets!
Well... not exactly.

 Magnetoid chromaticity, a physical property of the pandimensional realm, is a little more complex than that. In simple terms: walls attract objects of the same color. All kinds of objects!
Like big boxes. Or small boxes. Or medium boxes!
Or the completely safe, friendly, and definitely not murderous WorkerDroids*.
(Non-exhaustive list)

Use your refined painting skills and color mixing to voluntarily solve intricate puzzles on the ChromaTec ChromaGun Research Test Track, Model II — also known as ChromaGun 2.
