That is true, just checked. But, I wouldn't say that those colours you get are wrong. Sometimes you don't always get the most dominant ones. You can still get purple by bumping up the "accuracy" level up to 8 (which is not really "accuracy"). However, blue colour seems to appear only when palette size is set to 7. This is why I've introduced "fine tune" and "skip" features, to be able to tweak colours.
