Dark fluid on ground near Gas filler Hose

[Nunya Bizznizz]

I just spotted a very dark fluid on the ground under my vehicle (almost 1 square foot in size) just in front of the rear driver side tire (gas filler neck is just behind driver side rear tire). It looks pretty much straight black on the ground but when I dab my finger in it, it stains my finger brown and it smells like gasoline. I’m not surprised that I have a gas leak, because I have like 3 evaporative system codes, but I am surprised to see it’s so dark. Any ideas why?

If it is fuel leaking it could be washing off undercoating from you vehicle or the ground under your car was already oil stained or dirty.
