    Why doesn't this work? If you zoom in on the image at runtime, you'll notice that the top is red and the bottom is green, but at the transition between them, there is a dark line. It's my understanding that if you use the same offset for two colors, you'll get a hard break. By my math, 0.611111111111111 * 18 = 11, so its not like I'm giving it half pixels or anything. If I use .5 / .5 for the offsets, I get a hard break.

      Try experimenting with a less accurate number, I have found xaml does not play well beyond 2 decimal palces.

        It's not the "math"; it's the UseLayoutRounding setting (or lack thereof).
