Royal Blue

A saturated mid-depth blue with no green in it, even and strong, reading as pure blue rather than navy.

Next to an indigo this one is brighter and more open, staying visibly blue in low light instead of sinking toward black. It goes down easily because blue pigment is large and deposits well, so coverage tends to be even on the first pass. The fade is the awkward part: as the blue softens, the yellow underneath begins to show and the color slides through teal on its way to green.

  • Undertonecool. Cool and deep neutral skin handles it best, because a blue this saturated casts cold light onto whatever sits next to it.
  • Starting pointLevel eight will take it, so a full lift to white is unnecessary, though the more yellow left behind the faster it slides to teal.
  • UpkeepSix to eight weeks of wear is realistic, with a teal stage somewhere in the middle, and blue is slow to strip when you finally want it gone.

Questions about Royal Blue

Which skin undertones suit Royal Blue?
Cool undertones. Cool and deep neutral skin handles it best, because a blue this saturated casts cold light onto whatever sits next to it.
What hair do I need to start with for Royal Blue?
Level eight will take it, so a full lift to white is unnecessary, though the more yellow left behind the faster it slides to teal.
How much upkeep does Royal Blue need?
Six to eight weeks of wear is realistic, with a teal stage somewhere in the middle, and blue is slow to strip when you finally want it gone.
How do I choose the right shade of blue hair?
Start with your skin and your base. Cool and deep neutral skin carries a saturated royal blue best; fair skin with pink undertones can go lighter, toward cornflower or pastel blue; warm skin often looks better in teal or a deep navy that sits closer to black. For blue extensions, match the brightest part of your own colored hair, or choose navy to blend into dark hair.
Why does blue hair turn green?
Blue fades to reveal the yellow left in lightened hair, and blue over yellow reads green. Lifting to a pale yellow before coloring, refreshing every six to eight weeks and using a blue depositing conditioner keep it blue for longer.
Can I try Royal Blue on my own photo before I dye my hair?
Yes. HairGlam puts Royal Blue on a photo of your own hair in a few seconds, so you can check it against your skin tone and eye color before you book or buy a box dye. It is free to download on iPhone and iPad with 12 free looks: 4 haircuts, 4 hair colors and 4 makeup looks, and some looks can also be tried free in your browser at hairglam.app/try.
