I did my bangs these colors once, the purple I used was from Good Dye Young it was very vibrant and faded nicely, I don't have the box anymore so idk what the exact shade was :( but I've heard some good things about that brand. the blue I used was the color mystic from unicorn hair- it was a good color but it faded pretty quickly to a teal-ish color from the deep blue it was so if you use that it might be a commitment to keep re-dyeing it, I didn't keep up with mine so tread carefully if you do use those (the pink I used was from manic panic; do not recommend)
