Hume- missing blue Dotto

even before this class, i was fascinated by the idea that there is an infinite number of in-between mixtures. meaning there's a a color in between lightblue and dark blue, and there's another color between that medium blue and dark blue, and other medium, and another medium and so on. i would say that he is spot on with this theory but the only time it becomes a problem is when it becomes impossible to see with the human eye, or if its impossible to create with current technology. ( ever try to match a color with a new can of paint? even the same formula produces a slightly different shade, nevermind trying to mix an infinitely divided color.
