I wouldn't call it ridiculous, but... there is such thing as Black Lightning used by Darui and A (Third Raikage), but neither of the users can use the Yin nature. And the Six Paths Yin Power does not make Sasuke's Chidori black, the Six Paths Power does, also proven when Kakashi used the SP Power to make his Lightning Blade black, as I said above.

There's also Sage Art: Yin Release Lightning Dispatch, which supposedly produces black lightning (but that was only according to only one illegal scan that is known to make mistakes when translating Japanese raws), and it's only Yin Release and not Lightning Release at all, and the databook didn't refer to it as black.

There is also black ice, but that still isn't Yin Release either.

Basically, is there any proof that Yin turns elements black? I'm not seeing any. Looks like Blaze = Fire + Yin doesn't make much sense here, since Yin hasn't been proven to make elements black (unless I'm wrong?).

EDIT: And now that I think about it, we still haven't seen the color of Sasuke's Chidori or Kakashi's Raikiri in the anime after they apply the Six Paths Power, so we don't know if they truly are black in color (though it's plausible).
