I used this dye for highlights only, and it looked so beautiful with the Atlantic Blue dye. The color is vibrant and pretty bright. Lasts for a couple of weeks [I encourage conditioning, for it made the dye stay longer on my hair thanks to that], and fades to a pale blue and, sometimes, green. It turned green on the parts of the hair that were still a bit yellow after bleaching. It does stain a bit while styling the hair, especially when using hair spray, but the color doesn't stay on the fingers after washing the hands.
