You can't really dye a wig black..not a true black, it'll be a dark charcol-y grey color. Dying wigs doesn't work like that.
If I were you, I would get a black wig and sew in some fringe bangs, or short pink wefts.
Arda just got fringe bangs:
You would have to dye them pink though, as it appears they don't come in pink.
Or, I would get wefts from Doctored Locks.
Good luck! =^^=
