What Manic Panic "Electric" Hair color will work best on my unprocessed dark hair?

I'm looking to temporarily dye my hair, just to experiement, meaning I don't want to commit or risk the damage of bleaching my hair. I love my hair, and I don't want to hurt it with permanent color or bleach. But I still want a bold color. I know that's a lot to ask and all, but I only want that tint or color on my bangs, the rest will be their "Raven Black", as I know that it works on dark hair. I researched, and I think that Manic Panic is the only temporary dye that's not harmful and actually good for it. [Right?!] So I won't be quick to try something else. ANY answer would be greatly appreciated.
