Zoom into one of the two sizable filaments flanking the spike and you'll find a large minibrot surrounded by lightning. Go into seahorse valley shallowly and go for a filament to find a loose embedded Julia. Go close to its core minibrot and then aim for another, tinier minibrot, and along the way you'll get this.
One layer provides a color tint and the other is an additive greyscale DE layer.
