How to Choose Your PMU Brow Color: A Brown-Shade Guide by Skin Tone, Hair Color and Personal Color

1. Start with your undertone: telling warm, cool and neutral apart

Skin tone has two separate components: how light or dark it is (depth), and the hue sitting underneath (undertone). When choosing a brow color, undertone matters more. Two people who wear the same foundation shade can look completely different with the same brown if one has a yellow cast and the other a pink cast. Put a cool ashy brown on warm skin and the brows look dull and disconnected from the face; put a strongly reddish brown on cool skin and, over time, the brows can start to stand out as noticeably red.

If you're testing at home, it's better to cross-check several methods, since relying on just one is easy to get wrong. If the veins on the inside of your wrist look closer to green, you're likely warm; if they look blue or purple, cool; if it's a mix and you can't decide, you're probably neutral. Hold a sheet of white paper next to your face: if your face looks yellowish, you lean warm; if more pink comes through, cool. Whether gold or silver jewelry suits you better is another clue. If you tan to brown quickly in the sun, you tend toward warm; if you go red and rarely tan, you tend toward cool.

Many Koreans have a baseline yellow cast, so people often label themselves "warm" without a second thought, but in reality quite a lot of them are neutral. People with facial redness, or who flush only on the cheeks, can also mistake themselves for cool based on their cheek color. It's more accurate to judge by the skin on the forehead and around the brow bone, where the pigment will actually go. If you've had a personal color analysis, pass the result straight on to your artist at the consultation; it gives them an easy starting point.

• Leaning warm: greenish wrist veins, face looks yellow next to white paper, gold jewelry suits you, you tan easily
• Leaning cool: blue or purple wrist veins, face looks pink next to white paper, silver jewelry suits you, you go red in the sun
• Leaning neutral: the signs above come out mixed, and neither side's colors look especially off
• Where to judge: look at the forehead and brow bone rather than the cheeks (avoids being misled by redness)

2. Just as important as skin tone: hair color and eye color

The rule of thumb used most often in real consultations is "one or two shades lighter than your natural hair." Brows cover a much smaller area than your hair and sit right in the middle of your face, so at the same depth they read far stronger. That's why someone with near-black natural hair usually starts from dark brown rather than black, and someone with natural brown hair from around medium brown. Match your brows exactly to your hair color and in photos the brows tend to be the first thing anyone sees.

Eye color is a bigger variable than most people expect. Most Korean eyes fall somewhere between deep brown and blackish brown, but if your irises are closer to a light brown, going too dark on the brows creates a big contrast between brows and eyes, making the eyes look relatively washed out. Conversely, if your eyes are very dark and your lashes thick, going too light leaves the eyes crisp and the brows looking empty. Keeping the contrast between eyes and brows from getting too wide generally looks most natural.

Your own brow hair color needs to be factored in too. The procedure deposits color into the skin between your existing brow hairs, so if you still have hair there, the result reads as a blend of hair color plus pigment color. If your brow hairs are dark and dense, the overall look will be plenty defined even if the pigment is set a shade lighter; if you have very little or very faint brow hair, keep in mind that the pigment color simply becomes your brow color.

3. The impression each step of brown gives

Brow pigment names differ from brand to brand, but in actual consultations they're roughly grouped into the steps below. Even pigments with the same name can differ by brand and by how the artist mixes them, so talking in terms of "which step and what undertone" rather than product names leads to fewer misunderstandings.

A common mistake when choosing a step is basing it on "the final depth I want from day one." With PMU, the color typically fades by around 30–50% after the first session as the flakes shed, and is then built up at the touch-up. So choose the step based on the color that remains after healing, not how dark it looks right after the procedure. If it's your first time, starting one step lighter and deepening it at the touch-up is easier to walk back. Touch-up timing and aftercare are covered in a separate article, so here we focus only on choosing the color.

• Light/soft brown: a soft, bright impression. Tends to suit people with light dyed hair, faint brow hair, or a light makeup routine. Too light and the brows may look empty on no-makeup days.
• Medium (natural) brown: the safest choice. Low risk of a miss on natural brown hair and neutral skin.
• Dark brown: a crisp, polished impression. Balances well with black hair, blackish-brown eyes and strong features.
• Gray/ash brown: a calm tone with a gray cast. Used to tone down redness, but on cool skin the gray or blue cast can become more noticeable over time, so the ratio needs adjusting.
• Near-black: rarely used on its own. It tends to turn blue or gray over time, so it's usually mixed with brown.

4. What to go by if you dye your hair

A question that comes up all the time in consultations: "I've just dyed my hair ash brown. Should my brows match?" The basic answer is to match not your current hair color but the average color you'll mostly be wearing over the next one to two years. Hair color changes every few months, but brow pigment typically stays for one to three years. If you put in light brown to match bleached hair now and go back to black six months later, the brows will look too light and float on the face; the opposite case leaves the brows looking heavy.

If you change your hair color often, it's safest to land somewhere between your natural and dyed colors, usually around medium brown. A realistic approach is to lay down a base color with PMU, then match the surface color with brow mascara or shadow whenever your hair changes. If you keep one particular tone for a long time, say you always dye your hair a reddish brown, you can add a touch of warmth, but it's better not to carry the hair's redness straight over to the brows. Pigment in the skin tends to leave redness more pronounced than hair dye does.

If you're at the stage where gray or white hairs are increasing, some people choose one step less depth, anticipating that their hair will get lighter. Life plans like this are easy to miss if the artist doesn't ask first, so mention them yourself at the consultation.

5. Why brows turn red or blue over time: mixing with color shift in mind

PMU brow color changes over time because the pigment isn't a single ingredient but a blend of several colors. Brown pigments are generally made by mixing red and yellow components with black and blue ones. These components break down and clear from the skin at different rates, so once the faster-fading part is gone, the remaining color shows through. If the yellow fades first, the brows lean red; if the warm components fade first, they lean gray or blue. The speed depends on UV exposure, skin turnover, exfoliation habits and oil production, so the same pigment gives different results on different people.

That's why an experienced artist mixes not just for "a color that looks good now" but also for "the color that will remain about a year from now." For people who are cool-toned, or who have thin skin with visible veins, a gray or blue cast tends to emerge over time, so artists sometimes add a small amount of orange or warm corrector pigment to balance it in advance. Conversely, on warm-toned skin where redness comes up easily, a small amount of olive or green corrector is mixed in to keep the redness down. The correction ratio varies by artist and there's no single right answer, so a good way to check is to ask directly at the consultation: "Which way does this color tend to shift over time?"

If color from a previous procedure has already turned red or blue, it's no longer a simple matter of picking a color but one of color correction. That's covered in detail in our separate article on residue and color correction. The one thing to remember here: if the color is mixed with its shifting tendency in mind from the first procedure, you're less likely to need correction later.

• Cool-toned, thin skin, visible veins: tends to lean gray/blue → discuss adding a small amount of warm corrector
• Warm-toned, flushes easily, facial redness: tends to lean red/orange → discuss adding a small amount of green/olive corrector
• Oily skin: color tends to blur or fade faster, so a very light shade may look empty sooner
• Lots of outdoor activity or sun exposure: shifting and fading may speed up, so sun-protection habits are needed alongside

6. Concrete ways to check the color at your consultation

Color looks very different depending on the lighting. Studio lighting is usually bright, white daylight-type light, which makes colors look cooler and lighter than in everyday life. Going through a few checks at your consultation reduces the chance of "It looked fine at the studio, but it looks red now that I'm home."

The most reliable method is a daylight test. Have the artist dab a little of the mixed pigment, or a pencil in the same shade, on one brow or the inside of your wrist, then step over to a window to look. Bright shade by a window is closer to the color you'll actually see day to day than direct sunlight. Taking a front-facing photo on your phone without flash also gives a more objective view than a mirror. Putting two candidates side by side, say candidate A on the right and candidate B on the left, makes the decision much quicker.

Another is to check it in your everyday look. Go in wearing your usual makeup, with your hair down or tied up the way you normally wear it. A color chosen on a bare face can look faint on makeup days, while one chosen with heavy makeup can look strong on a bare face. Think about which face you see more often, your workday look or your weekend look, and set your baseline accordingly.

• Daylight test: apply the pigment or a matching pencil and check it in bright shade by a window
• Photo check: take a front-facing photo without flash and compare it with one taken under indoor lighting
• Side-by-side comparison: put the two candidate colors on separate sides and compare them in one frame
• Your everyday look: visit with your usual makeup and hair
• Questions to ask: the name of the pigment and whether a corrector is added, which way it's expected to shift after a year, and how much the color can be adjusted at the touch-up
