Ever tried to paint a Miku figure or design a fan site and realized that "teal" isn't actually a color? It's a trap. You go to Google, type in a quick search, and you get fifty different answers. One site says it's seafoam. Another says it's cyan. Your monitor makes it look like a neon emerald, while your phone says it's a dusty turquoise.
Miku’s hair color is a moving target.

Honestly, the Hatsune Miku hex code colors aren't just one single string of numbers. Since her debut in 2007, she’s been reimagined by thousands of illustrators, and Crypton Future Media itself has shifted the palette depending on whether they're selling a software update or a life-sized statue. If you want her to look "right," you have to understand the specific color theory behind the Vocaloid 01.
The Original 2007 Palette: Where it All Started
KEI, the original illustrator, didn't just pick a random blue. He was looking at the Yamaha DX7 synthesizer. That’s the "lore" reason for her aesthetic. The DX7 had these very specific teal/blue-green buttons and accents. That is the DNA of her design.
If you’re looking for the most "authentic" version of that classic look, you’re usually aiming for #39C5BB.
This is the holy grail. People call it "Miku Blue" or "Miku Green." In the design world, it sits somewhere between a bright turquoise and a soft cyan. It’s got a high saturation but enough green to keep it from feeling like a generic "web blue."
But wait.
If you look at the official 01 tattoo on her arm, that’s a different story. That red is usually #E12885. It’s a sharp, magenta-leaning red. Most people just use a generic red, and it looks... off. It looks cheap. The contrast between that specific pinkish-red and the teal is what makes the character pop. If you get the hex code for the red wrong, the teal looks muddy.
Why Your Monitor is Lying to You
Here is the thing about hex codes: they are digital instructions, not physical reality.
When you see #39C5BB on an OLED screen, it looks electric. On an old LCD office monitor? It looks like a hospital wall. This is why professional cosplayers and merchandise designers don't just use one hex code. They use a palette.
For her clothing, specifically that metallic grey vest, you aren't looking for a flat grey. You’re looking for #868B8E or something with a slight blue tint. Miku’s "black" isn't actually #000000 either. It’s usually a very dark charcoal, like #323338. Using pure black makes the illustration look flat and lifeless. It kills the "digital" vibe.
The Version 4 (V4X) Evolution
When Miku V4X came out, things got complicated. The art style shifted. The colors got softer, more gradient-heavy.
- The Main Hair: #45D1C5 (A bit brighter, more "airy")
- The Shadows: #2E9E95 (Deep, ocean teal)
- The Highlights: #C0F7F2 (Almost white, but still holding that minty hue)
You see how the jump from #39C5BB to #45D1C5 changes the whole mood? The V4X palette is much better for modern web design because it’s less "harsh" on the eyes. It feels premium. It feels like a high-resolution vocal synthesizer rather than a 2007 computer program.

I’ve seen artists spend hours trying to color-match a 2K resolution wallpaper only to realize the artist used a 15% opacity purple layer over the whole thing. That’s the secret. Miku’s hair is rarely just one color. It’s a gradient from a deep teal at the roots to a bright, almost glowing cyan at the tips of those massive twin-tails.
The "Official" Brand Colors vs. Fan Art
Crypton Future Media actually provides brand guidelines for collaborations. If you’re a company like Toyota or Sony and you’re making a Miku-themed product, they don't just tell you "make it blue."
They use Pantone.
Specifically, Pantone 3258C is often cited as the closest physical match to her hair. If you convert that back to digital, you get something very close to our friend #39C5BB.
But fans? Fans do whatever they want. And that’s okay.
If you look at the "Snow Miku" variations from the Sapporo Snow Festival, the Hatsune Miku hex code colors go completely out the window. You’re looking at icy blues like #B3E5FC and snowy whites. If you’re doing a "Sakura Miku" design, you’re pivoting to #FFB7C5.
The point is: context is king.
A Quick Cheat Sheet for Digital Artists
If you’re opening Photoshop or Procreate right now, don't just sample a pixel from a blurry JPEG. Use these as your starting points:
The "Classic" Setup
Hair: #39C5BB
Skin: #FFF5EE
Tie/Accents: #3FD3C7
Sleeve/Vest: #5C5E60
The "Modern" (V4X) Setup
Hair: #45D1C5
Skin: #FDF1E8
Secondary Teal: #279B91
Dark Accent: #3B3C3F
The Psychology of the Miku Palette
Why does this specific combo work? Why do we care about a hex code?
It’s the contrast between "nature" and "machine." Teal is a color that exists in the ocean and the sky, but in this specific saturation, it looks synthetic. It looks like a LED. Pairing that with the dark, metallic greys of her outfit creates a "Cyberpunk Lite" aesthetic.
When you get the hex code wrong—if you make it too green—she starts looking like a forest sprite. If you make it too blue, she looks like a generic pop star. That 50/50 split between blue and green is the "uncanny valley" of Vocaloid design where she feels exactly like herself.

Practical Steps for Implementation
If you are a web developer or a designer trying to use these colors, stop using them at 100% opacity for backgrounds. It’s blinding.
Instead, use #39C5BB as an accent color. Use it for buttons, for borders, or for glowing text effects. Use a very desaturated version of it, like #F0F8F7, for your background color. This keeps the Miku "vibe" without making your users' eyes bleed.
For cosplayers painting props: don't trust your phone screen. Go to a hardware store and look at paint swatches in natural sunlight. Bring a high-quality printed reference of the official V4X box art. Look for a "Bermuda Turquoise" or a "Tropical Teal."
Getting the "Glow" Effect
Miku's hair is often depicted as having a bioluminescent quality. You can't achieve that with a single hex code.
To recreate this in digital art, use #39C5BB as your base. Then, create a new layer set to "Add" or "Screen" and use a soft brush with #96FFF7. Lightly tap the edges of the hair where the light hits. This creates that iconic "digital goddess" glow that defines her modern appearances in the Project DIVA games.
If you’re working on a UI project, try using a CSS linear gradient: linear-gradient(135deg, #39C5BB 0%, #208A81 100%). This gives the color depth and prevents it from looking like a flat block of 1990s web color.
Finalizing Your Palette
Choosing the right Hatsune Miku hex code colors depends entirely on which "Miku" you are trying to evoke.
- For 2007 Nostalgia: Stick to #39C5BB and high-contrast blacks.
- For Professional Design: Use the softer #45D1C5 with plenty of white space.
- For Darker Themes: Lean into the #2E9E95 shades and metallic charcoals.
The most important thing is consistency. Once you pick a hex code, stick to it across your entire project. Miku is a brand as much as she is a character, and brands live and die by their color identity.
To move forward with your project, start by creating a "base" swatch library in your software of choice. Save #39C5BB (Teal), #E12885 (Pink-Red), and #868B8E (Grey) as your primary colors. From there, generate shades and tints by adjusting the brightness by 10-15% in either direction to ensure you have enough range for shadows and highlights without losing the core identity of the character.
