Mermaid-inspired hair colors have been trending for a while now, and the fervor only seems to continue escalating. After all, there are so many ways to interpret the concept. Come Halloween, mermaid costumes continue to be one of the most consistently searched on the Internet. 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—whether you're dressing up for a holiday or channeling these sea-dwelling creatures in your day-to-day.
Luckily for you, we totally have your back. Once you've decided on your undulating style of choice, we recommend sifting through the below 43 shade options to seal the mystical deal. Truly, the sky (or should we say the sea?) is the limit when it comes to mermaid-perfect hair colors. Celebrity hairstylist and owner of Hair Addict Salon, Michelle Cleveland, defines mermaid hair as "long, flowy locks in a vibrant color and tone."

"To achieve these vivid shades, you first need to pre-lighten the hair," says George Papanikolas, Matrix celebrity colorist. "The more pastel a shade you choose, the lighter the pre-lightened hair will need to be, so darker hair would have the easiest time staying in the Fuchsia/Red/Orange/Yellow family. Blue and Greens would need to be pre-lightened to pale yellow."
Mermaid Hair Color
Choosing A Shade: The sky's the limit when it comes to mermaid hair. "Since these shades are not technically 'natural,' you really have the freedom to choose your favorite fun shade," Papanikolas says. Check out some images on Pinterest to get ideas.
Maintenance Level: High. It depends on the look you go for, but generally, unnatural shades require more upkeep to stay vibrant and conceal roots.
Goes Great With: Everything. Any skin tone and hair texture can try mermaid hair. The look is so easily customizable and encompasses a wide variety of shades. The key? "Work with what you got!" Cleveland emphasizes. "For example, eye color, skin tone, and hair color should all harmonize and balance to achieve the perfect result. If you have warm color eyes and skin, then it would be ideal to opt for a cool-toned hair color shade."
Price: $14+ for DIY semi-permanent, $50-$200 at a salon (price will vary based on whether you do all-over color or highlights)

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 have you believe, you don't need natural length or pounds of extensions to pull off the ultimate mermaid-perfect hair color. We love Keke Palmer's pop of lilac.

If you have a flair for the fiery, this hot magenta hue is kind of like Ariel's signature shade of crimson—but a heck of a lot cooler.
"I tend to recommend staying in the Pink/Fuchsia family since these tend to fade easily," Papanikolas notes. "The Blues/Greens have a tendency to stick to the hair and are much harder to remove if you want a change."
Rose gold hair has been having a major moment for, well, years. For an edgier take, we love the ashiness of this mauve shade.
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).
However, if you do want to follow Ariel's trademark shade of red almost exactly, we think we've found a match.

Sporting rainbow hair doesn't necessarily mean going with a dare-to-be-different shade like lime green or bubblegum pink. This burnt orange is bold enough to make a statement while maintaining a bit more subtlety.
Adding a bright hue to naturally textured hair makes curls pop. To avoid fried, dehydrated spirals, use a lightweight oil that moisturizes hair without weighing it down, like Verb's Ghost Oil ($2).

This blend of blue, purple, and magenta seems somehow toned down enough to take this look from mermaid on the town to professional in the office.

Green and Purple Mix
Keeping these colors separate to avoid muddiness is the key to this rock-and-roll-meets-Beetlejuice option.
"Mermaid hair is definitely not a DIY project," Cleveland cautions. "Leave this process to a highly trained professional as there is a ton of science and theory involved in lifting the proper amount of your existing hair color out based on the target shade you are looking for. Additionally, a professional colorist will have the proper supplies to protect your hair as it goes through this very invasive process."
An unnatural mermaid shade looks especially chic and edgy on a chin-length bob.
Sunrise hair and sunset hair aren't all that different, but the deeper tones definitely give this look a twilight vibe.
