It's in fact positive black and negative white chakras and they aren't yin and yang releases. Also just because most techniques besides elemental ones and taijutsu are either yin or yang release doesn't mean Naruto has YYR. Not only hasn't he shown any genjutsu, but also for all we know YYR may require a KKG or special skill.
