Yes, it's possible but it might smear.

if youre going for a blue/violet colour, they take best on pale hair. I bleached mine and the colour comes out really bright. my sister, who has dark hair, also bleaches hers where she wants bright colour. Depending on what brand you use, the colour may or may not come out very well on dark hair. A stand test (cut an inch of hair from the bottom and dye it) will show you what the colour will come out as.
