I've to admit I have no clue about machine learning, but what I notice is that this seems to have preferred colors for things that can actually have many different colors, most notably clothes. They're almost always this blueish slightly purple color here, even the samurai. Don't get me wrong, this is still awesome and I might try this on some old photos from my grandparents. I'm just wondering if and how one can prevent these things from picking this one ideal color for something and instead have it randomize a bit, since obviously you can't really know what color some jacket really was. (except maybe if the picture is a black and white photo of a PAL TV program.)
