Note that "9" is including transparency. It's an 8-color gradient, like the official JJ2 sets use for absolutely everything that they don't use a 16-color gradient for instead. Basically, the standard number of shades for a given color within a tileset. Nothing to worry about on that front. I'll see if I can figure out what "blurry" translates to on a pixel-by-pixel level and try to fix that.
