Personally, I would not put TOO much stock in the smoke color. That vision that Emma has is shown using some distortion filters, so we can't be sure of the color. Red and Purple can appear very similarly based on how the filter distorls the color.

However, I agree that Regina is the infamous red herring in this case. Though I have not ruled out the EQ. And the EQ has very good reasons to want Emma to suffer and die, not the least of which is Henry. Also, the EQ wants to make SNOW suffer, and killing Emma would go a long towards that end as well. Bottom line, Emma is a prime target for the EQ for multiple reasons.

I could see Gold being the person to do the deed, but only if someone is controlling him via the dagger. (and heaven help that person when Gold gets the dagger back).

I'd suggest Belle or Zelena as additional possibilities, but neither of them have shown to have skills with the sword.
