When it comes to minerals it can literally be a PPM scale that influences the color, look at sapphires and rubies, same mineral "Corundum" different color.
They would need to hit it with an XRF to find out what colored it
On a side note there are tons of old iron furnaces around here "The giant stone ones" and man made obsidian (The slag) is everywhere in the creeks. From bright blues, greens, to dark purples...
