11 Black Blue Hair Color Ideas You Need to Try Right Now

If you’ve been scrolling through hair inspo lately, you’ve probably noticed that black hair with a blue tint is having a serious moment. There’s something about the way blue catches the light against dark strands that looks moody, glossy, and kind of magnetic all at once. It’s not quite black, not quite blue, and that’s exactly the point.

This color combo works because blue is one of the few shades that plays nice with black without looking harsh or costume-y. Instead it just deepens everything and adds this subtle shimmer that photographs beautifully. Below are eleven ways to wear it, whether you want something barely-there or full-on statement making.

Edgy Blue Black Bob

A blunt bob dyed in a blue black shade has this sharp, graphic quality that instantly reads as intentional. The blue undertone shows up most in direct sunlight or under studio lighting, giving the cut a glassy, almost wet-look finish.

This style suits people with straight or slightly wavy hair since the blunt line needs a clean canvas to really pop. It works on round, oval, and heart face shapes especially well, and it’s a great pick if you’ve got fine to medium hair since bobs naturally create the illusion of thickness.

Styling is low effort here. A round brush blowout or a quick flat iron pass keeps the ends crisp, and a shine serum locks in that glossy look. Maintenance sits at moderate since blue tones can fade faster than straight black, so a color-safe purple or blue shampoo helps keep things fresh between salon visits.

Onyx Black with Subtle Blue Highlights

Onyx black with just a few blue highlights woven through is perfect for anyone who wants the effect without committing to anything loud. The highlights are placed so they only reveal themselves when your hair moves or catches light, which honestly feels pretty luxurious.

This works on basically any hair length and texture, though it looks especially rich on thick, dense hair where the base color has room to shine. It’s a favorite for people who want something office-appropriate but still a little different.

You don’t need much styling to make this pop, just loose waves or a simple blowout will do. Maintenance is fairly easy since the black base grows out gracefully and the subtle highlights don’t demand constant touch-ups.

Half Black Half Blue Long Shag

This one’s for the risk-takers. A long shag cut with one half dyed deep black and the other done in a rich, saturated blue creates a split-dye effect that’s bold without being chaotic thanks to the soft, feathered layers.

It suits people with long, thick hair who want their cut to do a lot of the talking, and it tends to favor those with an adventurous streak more than a specific face shape. Wavy or naturally textured hair enhances the shag’s movement even more.

Styling leans into texture, think tousled waves, a bit of sea salt spray, and scrunching rather than sleek smoothing. This is a higher maintenance option since you’re managing two different color zones, so expect more frequent toning appointments to keep both sides looking crisp.

Chic Short Hair with Dark Blue Black Hue

Short hair gets an instant upgrade with a dark blue black hue that reads sophisticated from every angle. Because the cut is short, the color has nowhere to hide, so every strand gets that rich, saturated depth.

This suits people with fine to medium hair since short cuts already add volume, and it flatters oval, square, and heart face shapes particularly well. It’s also a smart choice if you’re growing tired of maintaining length and want your color to carry the look instead.

A little texturizing paste worked through damp hair before drying gives you that piecey, tousled finish. Maintenance is easy to moderate, and root touch-ups are less noticeable on shorter styles since there’s simply less hair to grow out.

Long, Thick Black Hair with Blue Highlights

If you’ve got long, thick hair, you’re basically the ideal candidate for this look. Blue highlights woven through black hair create dimension that a single flat color just can’t achieve, especially on hair with enough density to show it off.

This style works for pretty much any face shape since the highlights can be customized around your features, framing the face where it’s most flattering. Straight or wavy textures both show the highlights beautifully, though curly hair can carry it too with slightly different placement.

Loose curls or beach waves let the highlights peek through as your hair moves throughout the day. Maintenance is moderate, and a glossing treatment every six to eight weeks keeps the blue from turning dull or greenish.

Jet Black with Blue Peekaboo Highlights

Peekaboo highlights are placed underneath the top layer of hair, so you only catch glimpses of blue when you tuck your hair behind your ears or throw it up. It’s a fun, slightly secretive way to wear color that still feels playful.

This suits people who want to keep things professional most of the time but reveal a pop of personality when they want to. It works well on medium to long hair and any texture, since the placement does the work rather than the cut itself.

Half-up styles, low buns, and ear-tucked waves are the best ways to show off the color. This is one of the easier options to maintain since the hidden placement means less visible regrowth and fewer urgent touch-up appointments.

Blue Black Skunk Stripes

Skunk stripes take the classic streaked look and give it a modern twist with bold, chunky sections of blue against a jet black base. It’s graphic, a little rebellious, and definitely not for anyone trying to blend in.

This style looks best on medium to long hair with some length to let the stripes fully develop, and it tends to suit those with a strong sense of personal style more than any particular face shape. Straight hair shows the stripe pattern most clearly.

Sleek, straight styling with a middle part really lets the stripes stand out, though you can soften the look with loose waves too. Maintenance runs moderate to high since the contrast between the two colors makes regrowth more noticeable.

Perfect Black Blue Ombre

Ombre hair fades gradually from one color into another, and in this case, black melts into a deep, saturated blue toward the ends. It’s a gentler way to wear blue since the color intensity builds gradually rather than showing up all at once.

Long hair is really where this technique shines, giving the gradient enough room to transition smoothly. It suits most face shapes and textures, though wavy or curly hair adds extra dimension since the color catches differently at each curl.

Beachy waves or a loose braid highlight the gradient beautifully. Maintenance is on the easier side since the darker roots grow out without creating an obvious line, meaning you can stretch out salon visits longer than with all-over color.

Stunning Blue-Black Layered Haircut

Layers give this color combo somewhere to go, and a well-cut layered style lets the blue tones catch light at every angle as your hair moves. It’s a great option if you want your color and cut working together rather than one overshadowing the other.

This suits medium to thick hair that can support multiple layers without looking thin, and it flatters round and square face shapes by softening angles. Both straight and wavy textures take to layering well.

A diffuser or round brush enhances natural movement, while a lightweight mousse keeps layers from falling flat. Maintenance is moderate, with color refreshes needed roughly every two months to keep the blue looking vibrant rather than washed out.

Black Swan with Deep Blue Highlights

Named for that dramatic, almost theatrical vibe, this style pairs a rich black base with deep, saturated blue highlights concentrated around the face and crown. It’s moody in the best way, like your hair has its own atmosphere.

This works particularly well on long, thick hair and suits oval or heart face shapes since the highlights are typically placed to frame the front sections. It’s a striking choice for anyone who wants their hair color to feel a little cinematic.

Middle parts and sleek, straight styles amplify the drama, though soft waves give it a slightly more romantic feel. Maintenance sits at moderate to high since the deep blue pigment needs occasional refreshing to stay saturated rather than fading toward gray.

Glossy Black Blue Balayage Waves

Balayage takes a hand-painted approach, so the blue tones look sun-kissed and naturally woven through rather than precisely placed. Paired with loose waves, this creates a soft, lived-in version of the black blue trend that still feels rich and dimensional.

It suits long to medium hair with a wavy or curly texture, since the natural movement helps blend the painted sections seamlessly. Most face shapes take well to this since balayage placement can be customized to highlight your best features.

A texturizing spray and loose curling wand work create that effortless wave pattern the style is known for. Maintenance is on the lower end since balayage grows out softly, making it one of the more forgiving options on this list if you’re not into frequent salon trips.
