I'm not claiming any chemical knowledge whatsoever but I was thinking why is the heavy oil symbol red/brown and the fluid in the pipe blue ? Why do sulfuric acid, light oil and lubricant need to have such similar colors ? And why am I making such a trivial topic ? Food for thought.

He makes a good point.

I think a bright yellow would make a nice acid color, its the color of sulfur, its shown in the center of the sulfuric acid atom icon, and yellow just seems 'dangerous' like acid would be.

Heavy oil could indeed be a red/brown to match its in game icon.

Green lube does not make much sense, but hey its green now so it can stay green if sulfuric acid was no longer green. I guess green is a color for acid/caustic stuff in games hence why sulfuric acid is green but meh. Light oil kinda takes the pale yellow/brown color that lube could otherwise be.
