Billie Eilish Names the Hair Color That Matched Her Soul—And Fans Totally Agree

Billie Eilish has never been one to shy away from bold self-expression, especially when it comes to her ever-evolving hair color. From pale white to denim blue, fiery red, and jet black, her hair has become as iconic as her music. But among all these looks, there’s one color combination that stands out as deeply personal—and a fan favorite: the striking green and black.

The Hair Color That Defined Billie

In a candid April 2025 interview with British Vogue, Billie reflected on her favorite hair colors throughout her career. She singled out two distinct phases—her green roots and red roots—but emphasized the green and black era as something truly transformative.

“That shade of green was like my color for so long. I loved it so much,” she explained. “Hair, nails, clothes. It was such a magical period for me, and it was so intense. I felt like I was becoming who I am.” Worn from mid-2019 to early 2021, this look was more than a style choice—it symbolized her rebellion, creativity, and emerging identity during the critical rise to fame following her debut album.

Billie even joked that this hairstyle deserved its own nickname: “The Billie.”

A Contrast to Other Colors

While Billie’s natural hair is blonde, she admits she hasn’t worn it in a long time. Black hair, she shared in a Vogue video, “is kind of what feels the most like me, weirdly.” Yet, she distinguishes that black is more about comfort and continuity, not the identity-defining period she associates with green and black.

Interestingly, Billie also expressed a strong dislike for blue hair in a 2019 BuzzFeed interview, calling it her “least favorite color” and wondering aloud how she even ended up dying it that shade. This candid admission highlights just how special the green and black look was in contrast.

Why the Green and Black Means So Much

Billie’s green and black hair wasn’t just an aesthetic decision—it marked a time of personal and artistic self-discovery. This period coincided with the release of When We All Fall Asleep, Where Do We Go?, her Grammy-winning debut album that catapulted her into global stardom. Fans and critics alike embraced the look as a symbol of her edgy, unconventional style and fearless individuality.

Media outlets and fan sites have described this hairstyle as the visual embodiment of Billie’s unique spirit—bold, intense, and unmistakably her.

A Journey of Becoming

Billie Eilish’s reflections reveal how hair color can be more than fashion; it can be a statement of identity and growth. While black hair may currently feel like home, the green and black era remains the chapter where she felt she truly became herself—a “magical” and “intense” time that fans continue to celebrate.

In the world of ever-changing celebrity styles, Billie’s green and black look stands as a testament to the power of self-expression and the colorful journey of becoming who you really are.
