Well its easy to see why u would be perplexed by that! its so hard to tell! It could be either one. i have used fondant in candy molds however, and its easy and quite nice. You just need to dust the mold with some icing sugar/cornstarch first to prevent the fondant from sticking, then you just press the fondant in and wait for it to harden a bit before u remove it. The only problem (so i've been told) is that once you put icing sugar/cornstarch in the mold if u want to reuse it for chocolate/candies later they will not come out as shiny and nice.The icing sugar/cornstarch must scratch it or something. Perhaps you will need to just use it for fondant! Thats what i do. hth!
That looks like white chocolate to me. I've used fondant in candy molds before too, but it's not as smooth as what's pictured.
I agree with carmijok
