Blue hair is by far the coolest of the fashion hair colors. It exudes confidence and fearlessness, but without the attention-seeking vibe of other unusual hair colors. Blue hair color is becoming especially popular right now thanks to celebs like Lady Gaga and Kylie Jenner rocking pastel takes on it so far this year.

Now’s the fun time to explore some creative blue hair color photos and pick your next show-stopping look! Below, we’ve got some photos that will give you inspiration and show you all of the different ways blue hair can look.

1. Cloud Blue Hair

This silvery take on blue hair is as fluffy as a spring day cloud. It’s a balayage look that combines metallic, silvery-white tones with light pastel blue, which is more saturated near the roots but fades away delicately.

2. Deeply Rooted Blue Curls

Our obsession with metallic takes on blue hair color continues. This feathery curled hairstyle is super light and shiny thanks to a metallic wash of light blue over glistening white hair. What keeps this look grounded are dark, nearly black roots that add depth and keep things healthy.

3. Royal Treatment Blue Hair Color

This subtle wave gives the perfect retro accent to deep blue hair. The hair was colored with a royal blue hair dye, but there is also a vein of black running through the style as a lowlight, which adds depth and sophistication to the look.

4. Ocean Dive Blue Hair

As you look at these curls you get the feeling as though you’ve plunged into the very depths of the ocean. The twisted curls have a living tentacle vibe, while the black to blue to turquoise color gradient feels like the progression of color you see as you dive deeper and deeper into the waves.

5. Three-Quarter Blue Ombre

While true half-and-half ombres are becoming an increasingly rare choice for hair dyeing, ombres that leave the bulk of the lower part of the hair dyed one color are certainly on trend. This example shows us an ombre where the top half is a deep, rich blue, while the bottom half is a bright and cheerful sky blue.

6. Analog Blue Hair Melt

Colormelts are always obsession worthy, but analog colormelts most of all! The color progression here is violet to royal blue to teal, a cool transition that places primary blue front and center. The fact that the hair looks extra soft and lush makes the transition all the more gorgeous.

7. Ice Blue Waves

You have to be careful with this kind of take on blue hair color! It looks simultaneously so soft yet so icy cold – who knows whether the cold will sting when you touch it? It’s a look that features unbleached roots that have been simply washed with blue hair dye, while elsewhere the hair was taken as light as it could go, which means the wash of blue looks soft and metallic.

8. Dark Denim Blue Hair

The blend of muted black, navy, and royal blue hair dye in this balayage leads to a denim effect thanks to an organic streaking technique. It is especially nice if you’re low-maintenance when it comes to styling, since even this messier route ends up looking pretty darn cool.

9. Electric and Cobalt Blue Balayage

Blue hair can really make you feel like an anime character, especially if the shades of blue you choose are particularly vivid. This balayage combines true electric blue as the base tone and then adds cobalt blue as a slightly muted accent. What would be really intense ends up being charming thanks to soft curls.

10. Curled Black and Blue Hair

These lush hairstyles are giving a whole new meaning to the expression “black and blue”! Dark black roots are easy to pair with striking deep blue curls. By curling the hair in a bottleneck shape you can keep things romantic.

11. Stormy Ocean Blue Hair

Pairing waves with blue hair is a natural choice, since, of course, you’ll want to channel the ocean in your look. This deep and dark take on blue hair also has a bit of levity because of subtle touches of a lighter blue here and there along the ends of the hair.

12. Day and Night Sky Blue Hair

This hairstyle channels both the power of the night sky and the cheer of bright blue day sky. It combines deep black roots with lighter blue hair, with just a touch of royal blue making sure the transition is seamless.

13. Fearless Green and Blue Hair

If you feel like fearless and complex are words that describe your personality well, then give this hairstyle a good look: it combines royal blue and green hair tones in a way that has a lot of texture but still seems matte. What really elevates the sophistication of this dye job, however, is the touch of titanium at the ends.

14. Sleek Azure Blue Hair

As charming as waves and curls might be, sleek, straightened blue hair is undeniably more striking. This azure take on blue hair dye is perfect for summer, as it has just the subtlest hint of green to it, which lends freshness.

15. Bring Me that Horizon Hair

Horizontal hair dyeing techniques are all the rage, so it’s lovely to see them paired with blue hair color like in this look. The roots were kept dark, so they blend seamlessly into that initial layer of royal blue – that is, until we make the switch to an extreme horizontal balayage of baby blue and metallic lavender hair tones.

16. Midnight Gleam Blue Hair

Mixing different tones of blue hair dye is the best way to ensure that your color doesn’t look flat. This style combines a muted and deep violet blue with a more vivid royal blue, in an effect that maximizes volume.

17. Baby Light Blue Gradient

Once you’re done oohing and ahhing over these flawless retro curls, give this gradient a closer look. The deep blue to light blue to teal situation is complex right from the start, but the true magic of it is the use of babylights at the transition. The center of the blue hair is not simply light blue – it is actually a combination of light and royal blue tones that give maximum dimension.

18. Blue Jean Queen

Denim hair is a really fun sub-trend of blue hair, and it’s an especially great choice for anyone who’s a little afraid of vivid colors but who isn’t so keen on the extreme lightness of pastels. This kind of palette is achieved with a lot of different shades of blue applied in the thinnest streaks possible.

19. Starry Night Blue Hair

If you’re feeling particularly creative, take inspiration from the world of fine art. This starry night-inspired blue hair balayage features vivid shades of blue, with a bit of hair glitter to evoke the stars in the night sky.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (19)

20. Blue Steel Hair

There’s something about deeper metallic hair colors that is intense without being overwhelming, like this perfect blue steel look. It was created with a mixture of deep blue and dark silver hair tones, in a perfect balayage technique that makes this graduated bob haircut seem extra textured.

21. Ode to the Storm Blue Hair

A deep blue gradient on wavy hair always calls to mind a stormy ocean night, but this take on the look has a ray of light in it. The dark roots shifting to deep blue are already a great choice, but adding that hint of electric blue near the front brightens the look and elevates it.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (21)

22. Baby Blue Hair

It’s hard to make mistakes with a long cascade of healthy hair, but it will certainly tempt you to take some risks occasionally. This seemingly solid color is actually comprised of various shades of platinum and blue hair dye, applied by hand painstakingly in order to achieve maximum drama.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (22)

23. Electric Blue Graduated Curls

Sometimes it seems like fashion hair colors are only for those with impossibly long hair, but that’s not true! Even those with lob haircuts can become mermaids! This take on electric blue hair color combines bright cyan highlights with royal blue and ultramarine tones for an in-your-face style.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (23)

24. Cobalt Blue Sombre

Somehow, when the hair is very long, sombre hair colors end up looking soft and almost natural. The top layer of this sombre is a subtler cobalt blue with a cool violet touch, which transforms into a royal true blue for the bottom half.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (24)

25. Boho Braided Blue Hair

Just because you’re rocking fashion blue hair doesn’t mean you can embrace boho styling techniques! This complex baby blue dye job is only enhanced by the feathery way in which it was styled, with small braids add the perfect texture for the festival season.

26. Cotton Candy Blue Hair

This blue hair color is so sweet it will give you a cavity! The base color to this wavy hair look is a metallic silver that is only enhanced by pastel tones of blue and pink that give the most scrumptious cotton candy effect.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (26)

27. Blue and Tan Hair

It’s not very common to see blue hair combined with natural, warmer hair tones like in this dirty blonde and air-force blue sombre, but just because it’s uncommon doesn’t mean it shouldn’t be done! This is the kind of take on blue hair that is not too attention-grabbing and also allows for easy maintenance.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (27)

28. Icy Blue and Lavender Hair

Combining pastel shades of lavender and blue hair dye with silver hair is risky when the hair is shorter, because you can end up with an unintentional look. However, when the hair is long and well-styled, the effect is marvellously multidimensional instead.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (28)

29. Neon Pink and Blue Curls

This is a twist on blue hair that is reserved for those who are very comfortable sitting in their stylist’s chair, since the pink hair roots in this look will require regular touch-ups. It’s totally worth it for that unique pop of brightness through the otherwise electric blue look.

30. Simple Midnight Blue Hair

Gorgeous blue hair doesn’t have to be complicated – just look at this simple style? Rich and metallic midnight blue pairs perfectly with naturally dark roots, and as long as the hair is healthy there is enough natural shine.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (30)

31. Icy Blue Fishtail Braid

One way of embracing your roots when rocking any kind of blue hair color is to wear a full or semi fishtail braid. This particular braid shows off roots in an elegant, purposeful way, and it works especially nicely with this icy take on blue hair.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (31)

32. Blue Lavender Dreams

If you like a bit more romance in your blue hairstyle, consider a pale blue shade that leans towards lavender. Here this tone is mixed with silver streaks as well, leading to a complex and feminine look.

33. Prussian Blue Curls

If your hair is naturally almost black, then you absolutely must try deep Prussian blue at least once in your life! This kind of blue can be achieved with limited bleaching, but the effect is coolly striking.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (33)

34. Freezing Rain Curls

This rich combination of silver and baby blue hair tones brings to mind freezing rain falling from muted blue skies. It’s an intense look that is made even more memorable thanks to the depth dark roots bring.

35. Indigo with a Gleam

Bring on the indigo drama! This gorgeous indigo blue hairstyle is as astounding as they come, thanks to really impactful balayaging at the ends. The bulk of the hair was dyed with a rich indigo blue hair dye, but it’s jazzed up by touches of mint and violet tones at the ends.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (35)

36. Minty Fresh Blue Hair

This is another complex hairstyle that gives us a perfect analog color scheme. The streaks of teal and violet that run through this predominantly sky-blue look add interest and complexity without being in your face or overwhelming.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (36)

37. Watery Blue Ends

Hair can tell a story, and the story this variation on blue hair tells is of water flowing from a rock. Starting with black roots and transitioning them to gray at the midst is already complex, but adding the multidimensional blue tones at the ends makes for a brilliant color scheme.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (37)

38. Midnight Velvet Blue Hair

Doesn’t this soft and lush hair make you crave trying midnight blue hair? It’s oh-so-shiny thanks to a mixture of different dark blue shades, and styling it in lush curls only emphasizes the level of dimension.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (38)

39. Blue Feather Hair

These feathery waves look so soft you’ll want to take a nap in them! This effect is doubled by the choice of a softer blue hair color combined with some subtle lavender hair streaks.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (39)

40. Frozen Blue Curls

If you like to take inspiration from cartoons when choosing your next hair look, then give this iteration on blue hair a good look! The color story here is straight out of the film Frozen, with vibrant blue roots that transform into a gorgeous silvery tone as though they had been frozen by Elsa herself.

41. Electric Blue Waves

One of the best ways of emphasizing wavy hair is by utilizing a horizontal hair dyeing technique. The combination of electric blue and teal tones is always a safe one, but taking the risk to dye horizontally surely paid off.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (41)

42. Stormy Seas Blue Hair

The balayage gradient technique used here is perfect for showcasing a natural transition, like the one seen in the sky as storm clouds come in, or the way they are reflected in a wavy ocean. Starting with black roots, the hair is dyed in piecey streaks that start off royal blue and transition to a beautiful sky blue.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (42)

43. Pastel Blue Waves

Soft like a cloud, these pastel waves invoke calmness in anyone who glimpses them. This is the type of blue hair color that requires multiple bleaching sessions, but the results are worth the effort.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (43)

44. Oceanic Fringe

Baby streaks are always a lovely choice that showcases a colorist’s skill, but once they show up in the fringe they become something truly unique. We love this take on ocean blue hair that combines royal blue, baby blue, and teal tones.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (44)

45. Summer Sky Blue Hair

Blue hair can be cheerful and festive, as exemplified by this sky-blue hair color. Dark roots ensure painless grow out, while light sky-blue streaks liven up a vivid royal blue base.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (45)

46. Oil Spill Blue Hair

In real life, an oil spill is a terrible thing, but there is nothing wrong with being inspired by its colors to create a hair masterpiece! Shades of cyan and electric blue are a natural fit, while violet runs through them to give extra drama.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (46)

47. Azure Sombre

Long hair is the perfect canvas for all kinds of two-tone blue hair dye creations, and we gotta admit this one is one of our favorites. The azure and baby blue combination is a classic, but it’s the careful transition that makes our hearts go aflutter.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (47)

48. Midnight Blue Balayage

The diagonal gradient in this balayage is the stuff dreams are made of, so it is fitting that it was created in dark shades like black-blue and midnight blue, with just a hint of royal blue and cyan for added dimension. It’s a great option for those with naturally dark hair, as it only requires a hint of bleaching.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (48)

49. Deep Sea Blue Hair

Those blends of dark blue and royal blue are already gorgeous, but the moment a bit of green is added to them they take on a slightly sinister, oceanic vibe. You never know what is lurking down there in the depths, along with the sea greens and waves.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (49)

50. Teal Blue Hair Colormelt

If your coloring is on the warm side of things, then blues with a touch of green to them will be the most flattering to you. This blue to teal colormelt is as subtle as it gets, and yet the result is astounding.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (50)

51. Sky-Blue Lob

Yet another example of how well blue hair color works even with traditional long bob haircuts! We’re really loving the way baby blue babylights add a bit of texture to the sky-blue base color.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (51)

52. Contrasting Blue Hair

Matching roots and ends, with a contrasting shade in the center of the hair, create a look that we sadly do not see enough of. The cyan tone in the center is simply vivid, especially against the indigo shade at the top and bottom.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (52)

53. Blue Cloud Bob

Curled bobs are always cute, but doubly so when colored a soft, romantic pastel shade like this baby blue! The roots are actually colored a royal blue, which is a surefire way of keeping the scalp healthy against all that bleach pastels require.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (53)

54. Sapphire Balayage

It’s hard to resist hair that gleams like a precious stone. This sapphire-inspired look was achieved by using a royal blue hair color at the top, and transitioning it to lighter, green-heavy shades at the ends.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (54)

55. Sapphire Gleam Long Bob

Don’t stare at this sapphire blue hair for too long, or you may find yourself incapable of looking way! The royal blue and sky-blue tones play against each other to create impossible depth – the kind one can easily get lost in.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (55)

56. Dark Wash Denim Hair

The vivid tones are fun and all, but sometimes you want to fly under the radar with your fashion colors. That’s when matte finishes in deep blue and navy can really have their moment, giving the hair a trendy denim effect.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (56)

57. Glacial Blue Bob

This bob haircut is so cool it will make you forget about the ice caps melting! The glacial effect is there because of the icy metallic tips, while a steel blue base echoes the sky on a cold, overcast day.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (57)

58. Royal Blue Waves

The amount of deep blue hair dye used for this colorful creation is hard to imagine, because boy are these waves long! Blue is a royal color, so why not choose it if you have hair so long and lush that it is fit for a queen?

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (58)

59. Light to Dark Blue Colomelt

So while dark to light colormelts are considerably easier to achieve (and they don’t take nearly as much of a toll on the hair), there is room for breaking rules here and there by opting for the opposite. Keep the roots bright with a baby blue hair tone and let the ends get darker like the navy that we see here.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (59)

60. Blue Hair Threaded with Lavender

If all of these blue hairstyles are leaving you cold, perhaps the hint of lavender in this colormelt will win you over? The hint of purple warms up the sky and cyan blue tones, as well as adds some vibrancy.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (60)

61. Arctic Sky Balayage

Arctic blue hairstyles are never going to look dated because the gleaming silver icy tones are always going to be impressive while the blues will always feel uniquely cool. This long bob benefits from all of the dimension that comes with this color combination.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (61)

62. Cobalt Blue Bob

Balayaging a graduated bob haircut requires a true artist, as this cobalt blue hair proves. The balayage technique is perfect for keeping the hair healthy with fashion hair colors, and it is also perfect for adding volume to shorter hair.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (62)

63. Denim and Silver Waves

Like wearing silver jewels with an all-denim outfit, this wavy hairstyle combines the ultra-lux with the chic yet casual. Light blue and silver tones are a perfect combination for anyone who likes to be on trend.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (63)

64. Sea Queen Balayage

It’s not easy to keep multi-colored balayages looking so crisp, but here’s proof that it is possible! The winning color combination here is sky blue for the base, with a touch of teal at the center for just the barest hint of oceanic warmth.

65 Iridescent Blue Hair Color Shades for Your Inner Mermaid (64)

65. Mermaid Blue Hair

A hint of green here and a deep wave there is all it takes to turn blue hair into a worthy look for a mermaid princess! The roots were left unbleached for that healthy depth, while the ends were dyed with a mixture of different teal and blue tones for a gorgeous texture.
