<p>Well Yin is the power of imagination right? It gives form. So it might be able to alter properties and/or amplify them. Assuming Lightning Dispatch is Lightning release in some shape/form, it changed the way lightning moved, and looking at the way it wrapped around Naruto's Sage Rod, it doesn't(at least to my knowledge) react the same way other lightning attacks have(go straight through the target). I believe the databook says it captures the enemy as well.

The reason it is black is because, unlike Tayuyas worms, fire DOES have physical energy and Yin is feeding it. Fire is a real, physical thing.
