I guess, this is somewhat tangential and should not detract from this tool, but I really don't like this concept of just giving everything a hue (which I believe was established by Google's Material You).
It leads to worse contrast and too often, it's used as a replacement for personality, with which it stands at complete odds. You can't pick out of a catalog of 360 pre-made looks and expect it to be personal to you (not to mention that it's much less than 360 that are actually discernible).
