No, it is not a bug. You never told LinearSegmentedColormap that you wanted a map with other than 256 colors, which is the default. If you want a colormap with 3 colors, use a ListedColormap. In fact, as I wrote before, this, together with a BoundaryNorm, is the best way to handle the mapping of discrete colors.
