I forgot where you lived Kait but usually they sell Japanese/Asian branded hair dyes at asian malls/supermarkets. For the colour you want, on your black/dark brown hair it will show up as "dark brown" still. Those colours are hard to dye without salon help. Ive tried using that kind of colour before and it didn't even show up at all because my hair is super dark.
I heard bleaching damages the hair so I dunno =< For that colour I would go to a professional to do it.
