I have dark brown hair (I'm Asian), and I want to get my hair to a shade of purple where it will be tinted purple in sunlight, and perhaps show a little bit indoors. I know bleaching is terrible for hair, so I'm hoping to avoid it as much as possible. Do I have to bleach my hair at all to get that effect? Or will it just not show up at all?

I'm planning on using Jerome Russell Punky Semi-permanent Color Cream in Plum, but I'm open to better choices if you have them.
