Showed up vibrant on my bleached hair
color is very bright even on brown hair. I mixed pink and red together evenly and got a nice burgundy color that lasted 2.5 weeks (I washed my hair everyday with shampoo and conditioner) it may last longer than 2.5 weeks for you. Two tubes was enough for me and I have shoulder length thin hair that was previously bleached and color treated. When the color faded it faded to a reddish purple.
Used pink. My hair is dyed medium brown and it did not show up as pink as I would have liked, but still pretty.
