Can raw honey look dark and runny?
That seems normal.

All the "raw" means is that it was extracted from the honeycomb without significant heating. It's liquid to start with in the honeycomb, so it's normal for it to still be liquid when you get it. I don't know if I'd call it runny, it should still generally be a pretty thick, slow-flowing liquid, but it's not a paste.

The color is mostly just a function of what the bees were gathering. Dark is often more flavorful, probably a good thing, but depends on your tastes. Mass-produced honey is very often lighter, and wildflower honey (where the bees just get whatever they want) is very often darker.

I've definitely seen plenty of raw, unfiltered honey that looks liquid and roughly the darkness of the raw honey you bought, judging by the picture in the linked page. If anything, it's probably more common to find dark unfiltered honey, because the filtering can lighten it up a bit.

The "paste" you linked to looks like it's crystallized/creamed. There are a lot of tiny sugar crystals, making it thicker and opaque, which tends to make it look a bit lighter too. (It's not completely smooth, like "perfect" creamed honey, but it's a lot smoother than uncontrolled crystallization, so I think it's fair to call it creamed.) Raw, unfiltered honey does crystallize more easily, because it has more imperfections in it to jump-start crystallization, so it's not entirely surprising to see raw honey in that form. But raw honey certainly doesn't have to be that way.
