25 Rainbow Hair Color Ideas for Your Most Magnificent Mane

If you’re looking to change up your hair color with a trend that’s going to make a statement, allow us to point you in the direction of rainbow hair. The rainbow hair color trend is still going strong, so now is as good a time as any to saturate your strands with an array of colors for a truly head-turning ‘do.

Deciding between blonde hair, brown hair, and red hair can be tough enough, so trying to figure out which rainbow hair color is right for you is no easy task. To eliminate the added stress, we’re sharing 26 rainbow hair color ideas to help you achieve your most magnificent mane.

1. Pastel Rainbow Hair

If a bold, rainbow hair color is a little too intimidating, you can take things down a notch by coloring your mane with a subtler alternative: pastel rainbow hair. This hue will still include all the beautiful colors of the rainbow, but with softer, less saturated versions of each shade. Get the look at home with the L’Oréal Paris Feria Multi-Faceted Shimmering Permanent Hair Color in Smokey Pink, Smokey Blue, and Dusty Mauve.

2. Rainbow Undercut

If you want a work-friendly rainbow hair color, a rainbow undercut may be a good option. More about the style and less about color, an undercut is a style where the bottom third of your hair on the underside of your head is shaved off.  You can get custom patterns shaved into this section of hair, and best of all, you can create one-of-a-kind colorful looks that will be hidden from sight when the rest of your hair is cascading over it.

3. Gemstone Hologram

Sometimes it seems as though all the fun colors are meant for blondes, but not this one. This hair color embraces a series of gemstone colors placed throughout brown hair. Gemstone hologram hair is known for the way it’s both bright and reflective while showcasing darker hues.

4. Hidden Rainbow Roots

If you’re not quite ready to embrace an all-over rainbow color, consider getting hidden rainbow roots. Only visible when you run your hand through your hair, rock braided hairstyles, or perform the occasional hair flip, this hair color idea is perfect for those who want to experience the magic of a rainbow hair color without going all in. Use the L’Oréal Paris Feria Multi-Faceted Shimmering Permanent Hair Color in Rich Auburn True Red, Power Copper, and Downtown Denim for your own hidden rainbow hair.

5. Oil Slick Hair

Oil slick hair is all about having a solid surface hue with rainbow tints blended within it. Most often, the base color will be somewhere along the spectrum of blue smoke to ashy black, with bright rainbow colors of magenta, purple, cobalt, and green painted throughout.

6. Peek-A-Boo Hair

Not ready to shave off a third of your hair but still want to keep your rainbow hair on the DL? Consider getting a peek-a-boo rainbow hair color. To the naked eye, your hair will look  — but as soon as you have the opportunity for a hair flip (or wear an updo), you can let your pretty rainbow hair color stand center stage. Try the L’Oréal Paris Colorista Hair Makeup Temporary 1-Day Hair Color Spray in Red, Blue, and Purple for a temporary look before committing to something more permanent.  

7. Rainbow Cereal Hair

If you’re interested in taking your rainbow hair to brighter and bolder heights, feast your eyes on rainbow cereal hair. This hue keeps your base hair color intact and adds streaks of hot pink, yellow, orange, and green to your hair, and it’s ideal for those looking to shake things up without a full-color change.

8. Rainbow Grunge Hair

If you love to take hairstyle cues from your favorite rock stars, rainbow grunge hair will surely tickle your fancy. Featuring a gray base that transitions into rainbow shades painted throughout your mane, this hair color trend serves up the right amount of dimension and depth.

9. Neon Rainbow Hair

It’s safe to say that you have to love playing with color to give the rainbow hair trend a go. If you’re also partial to stepping outside-of-the-box, you may want to add neon rainbow hair to your must-try list. Offering everything you love about the colorful trend, this look provides your mane with an even bolder, more dramatic hue that won’t go unnoticed.

10. Rainbow Ombré Hair

If you prefer to mix all your favorite hair color trends into one, it’s time to get acquainted with rainbow ombré hair. Serving up a gorgeous transition of color with dark roots and lighter ends, this trendy hair color is just what you need to make a stylish statement. 

11. Glow in the Dark Rainbow Hair

The only thing that’s better than rainbow hair is rainbow hair that also glows in the dark. This super-chic and futuristic take helps you make a lasting impression wherever you go. During the day, beautiful and colorful rainbow hair, and at night a head full of glowing strands.

12. Dark Rainbow Hair

While bright rainbow hair is totally on-trend, you can switch things up with a darker hue, too. Perfect for those who love to take a walk on the dark side, a blend of dark blues, purples, and greens will add the right amount of edge and mystique to your look. Use the L’Oréal Paris Feria Multi-Faceted Shimmering Permanent Hair Color in Violet Soft Black, Turquoise, and Midnight Violet to get the dark rainbow look at home.

19. Geode Hair

The last thing on your mind may be to emulate a rock but in the case of geode hair, you may want to hop on the bandwagon. Featuring sparkling purple and blue tones that are used to mimic the look inside of a geode (geodes are filled with hollow cavities that are lined with crystals), it’s a creative and unique way to wear a rainbow hair color.

20. Tie-Dye Hair

Tie-dye was a popular trend back in the ’90s, and now it’s resurfaced on the hair color front. Inspired by the rainbow hair trend, this look requires the use of a hair marbling technique to swirl your hair color. The epitome of a unique and quirky look, this hair color will make your strands the talk of the town.

21. Color Block Rainbow

If you want your rainbow strands to stand out even more, try a two-toned look. One side of your head sports the bold rainbow shade, while the other flaunts your natural hair color for a chic, creative, and edgy look.

22. Dip-Dyed Rainbow Hair

A fabulous low-maintenance option, this look involves coloring just the ends of your hair, so you don’t have to worry about any touch-ups or uneven color during the growing out phase. You can also make this style even more low-maintenance by simply spraying L’Oréal Paris Colorista Hair Makeup Temporary 1-Day Hair Color in Blue, Purple, and Pastel Mint on your ends for a quick way to get dip-dyed ends.

23. Lavender Rainbow Hair

If purple hues are your forte, give your strands a tasteful and stylish mix of color with lavender rainbow hair. Blending dark blue, purple, and pink shades, this hair shade has a fantasy feel.

24. Chunky Rainbow Highlights

If you’re in the mood for a bold look, consider elevating your strands with chunky rainbow highlights. As the name suggests, this trend gives you thick and bold tinges of color weaved through your hair.

25. Rose and Lilac Pastel Hair
