The color: Jewel-Toned Rainbow
Description: The color technique is called Borealis. Michael Haase, Wella top artist and Salon Platinum Black owner, explained what this means: "[It is] a term coming from the magical Northern Lights, which include rich gemstone-quality hues with the slightest hint of fairy tale." Envision green, blue, pink, and violet tones that have richness and depth. Katy Perry's violet (pictured) is exactly on point.
Who it works for: This works for anyone who wants to showcase their personality and has time to make trips to the salon each month to keep the color in check.
Technique: Hair is usually prelightened to a light blond and then shades like amethyst are added. When booking your appointment, let your stylist know that you want to dye your mane a rainbow shade so that he or she can allot the appropriate amount of time. In most cases, booking a consultation is important.
