Colorful Oil Barrels

Here's a neat illustration featuring three different industrial barrels, each painted a distinct color. You can see a bright green one, a striking red one, and a dark, almost black barrel, arranged in a small cluster. They all have the classic drum shape with white banding and a simple opening on top. It gives a sense of storage or transport for various liquids, perhaps oil or chemicals.
