Mermaid-inspired hair colors have been trending for a while now, and come Halloween season, the fervor only seems to escalate. After all, the costume idea continues to be one of the most consistently searched on the internet, well, Pinterest. Alas, while you might have your mermaid hairstyle and makeup down pat, or at least in the works, adjusting your hair color to under-the-sea perfection is the cherry on top to achieve the ultimate finned masterpiece of a look this Halloween.
Luckily for you, we totally have your back. Once you've decided on your undulating style of choice, we recommend sifting through the below 25 shade options to seal the mystical deal. Truly, the sky (or should we say bottomless depths of the sea?) is the limit when it comes to mermaid-perfect hair colors.
Read on for inspiration. We've got styles and colors aplenty.
If you're looking for a color that still veers more natural, we love the versatility of Lucy Hale's lovely shade of garnet. So much, in fact, we think we'd continue to wear it even after we've shed our fins.
Loch Ness Lilac
Despite what Instagram and Pinterest might want you to think, you don't need naturally long length or pounds of extensions to pull off the ultimate mermaid-perfect hair color this Halloween. We love Keke Palmer's pop of lilac, which has a touch of fantasy to it.
Can't decide on just one (or two or three) colors? Why not swim full speed ahead and try a rainbow-striped vibe out for size? Bonus points for braids aplenty and whimsical touches of flora.
If you have a flair for fiery, this hot hue of magenta is kind of like Ariel's signature shade of crimson. Except, if we say so ourselves, a heck of a lot cooler.
However, if you do want to follow Ariel's trademark shade of red almost exactly, we think we've found a match with this gorgeous shade.
Ombré hair is still going strong, and honestly, the technique just screams mermaid. You can achieve the look with any collection of mermaid-inspired hair colors, but we're especially partial to the nuance of blues and purples.
Not quite goldenrod, not quite blonde, not quite orange, this sunset-esque hue has us transfixed. And yes, we think it would make for the perfect mermaid hair color.
For a step in the subtle yet still-sultry direction, this moody, inky shade of plum looks like it came straight from deep, dark depths of the ocean.
Love the idea of purple hair? Make the prospect even brighter with highlights of electric blue. It's less expected (and far more mermaid-appropriate) than just straight purple. Although that would, of course, be enchanting as well.
Rose-gold hair has had a major moment in the past few years, but to keep things a little edgier for Halloween season, the ashiness of this shade of mauve seems just a little more superior. Plus, it's kind of great for fall, in general—not just your typical Halloween festivities.
This dusty blush hue is reminiscent of Nicki Minaj's pick for pink strands and we are totally on board. Bonus: It looks great on all skin tones, too.
A little silver, a little blue, a little purple… We can't help but compare this shimmering shade to the flash of mermaid's scale-adorned tale.
The thought of green is nice for fit-for-a-mermaid hair, but the thought of an entire head of green hair can also be a tad intimidating. This spell-binding graduation from navy roots to aquamarine to bright lime feels (maybe?) more manageable and (completely) fantastical.
Adding a bright hue to naturally textured hair is makes curls instantly pop. To avoid fried, dehydrated spirals use a lightweight oil that moisturizes hair without weighing it down like Verb Ghost Oil ($16).
Somehow this blend of blue, purple and magenta seems toned down enough to take this look from mermaid on the town to business professional in the office (for some of us, at least). Either way, it's a dope hue no matter where you rock it.
Okay, these rainbow strands are a true work of art. From lilac panels to perfectly-placed colorful stripes, obsessed is an understatement.
This neon-painted buzz cut proves that mermaid hair isn't just for those with long, luscious locks. If you're looking for a temporary option, try the Manic Panic Amplified Color Spray ($10).
If you're in love with rainbows, this shade (or variety of shades) is for you. TBH, rainbow doesn't get better than this.
Sporting rainbow hair doesn't necessarily mean going with a dare-to-be-different shade like lime green or bubblegum pink. This burnt orange hair is bold enough to make a statement without going overboard.
Under The Sea Blue
There's blue and then there's blue like this impossible-to-miss royal hue. It's reminiscent of a blue raspberry lollipop and we love everything about it.
When you're feeling indecisive and can't settle on just one shade, opt for your top three faves like this gradient style of purple to blue to green.
Let's be frank. Yellow isn't the most popular shade in the world of hair color. After all, it can go from rad to bad really quickly (we recommend visiting a professional to achieve this color). But we must admit, these sunshine-dipped tips make golden hair totally aspiring.
Move over Ariel. This neon coral hair is what mermaid dreams are made of.
Mixing a trio of shades within the same color family gives this dimensional color a metallic finish without falling flat.
