Is It Disrespectful to Write Someone's Name in Red Ink in Korea?

Written by a Korean-born writer who spent three decades in the airline industry, sharing what growing up in Korea actually looks like.

Introduction: A Kindly Chosen Pen That Brought a Room to a Quiet Standstill

A foreign office worker at a Korean company wants to leave a quick note on a coworker's desk. The pen closest at hand happens to be red, so the foreign worker grabs it without a second thought.

They write their coworker's name at the top, and jot a short message below it. A little later, the coworker finds the note and gets a strangely tense look on their face. There's no anger in it, but discomfort clearly flickers across it.

The foreign worker has no idea what just happened, and finishes out the day none the wiser. The message itself was kind, and the pen color was just whatever happened to be within reach.

But in Korea, writing a person's name in red ink isn't just a color choice. It's tied to an old taboo that conjures up death and bad luck.

In short: Writing a name in red ink in Korea echoes the old custom of recording the names of the deceased in red on death registries and memorial tablets. The taboo is specific to red plus a name — not to the color red on its own.

A Custom Rooted in Death Registries and Ancestral Rites

The most widely cited origin of this taboo traces back to traditional funeral and ancestral rites across Korea and East Asia. In the past, Korea and China shared a custom of recording the names of the deceased in red ink on memorial tablets or registries.

Red functioned as a visual marker setting that name apart, signaling that its owner no longer belonged to the world of the living. As this custom passed down through generations, the act of "writing a name in red" itself became tightly bound up with the ominous implication that the person was dead, or that their death was being wished for.

The Two Sides of Red in Yin-Yang and Five Elements Thought

Within the eumyangohaeng (yin-yang and five elements) philosophy that underpins traditional Korean thought, red was never treated as a uniformly negative color. If anything, red symbolizes strong vitality and yang energy.

It shows up actively in traditional Korean wedding attire, protective talismans, and certain holiday decorations, believed to ward off evil spirits and invite good fortune. Red itself is not consistently treated as an unlucky color in Korean culture.

What matters here is that the taboo isn't located in the color red on its own. It's located in the very specific combination of "writing a person's name in red."

A red traditional wedding garment or a red talisman carries an auspicious meaning. But red lettering placed right next to a living person's name starts to resemble the entries in a registry of the dead. It's that specific pairing — red plus name — that hardened into a strong taboo in Korean society over a long stretch of time.

A Superstitious Feeling That Survives Into the Present

Most Koreans today don't know the precise origin of this taboo in any detail. But the emotional discomfort tends to linger instinctively, even without any explanation or formal teaching behind it.

It works in much the same way that Friday the 13th or black cats carry a vague sense of bad luck in Western culture. Most Koreans will say they don't actively believe in this taboo — and yet, the moment they see their own name written in red pen, a flicker of discomfort often passes through them anyway.

I still remember, as a child, reaching for a red pencil to write my name on a new schoolbag tag. My mother snatched it out of my hand before I'd even finished the first letter, and handed me a blue one instead without a word of explanation. I didn't understand why at the time, but I never touched a red pen for my own name again.

How strongly this sentiment shows up clearly depends on generation. Korean parents and grandparents tend to be sharply aware of this taboo, often reacting the moment they see a name written in red.

Among Koreans in their twenties and thirties, awareness has noticeably faded. Many younger Koreans treat it as "something older generations care about," barely conscious of it when jotting a casual note to a friend.

That said, even this younger generation tends to consciously observe the taboo in more formal settings — weddings, funerals, or any document their parents might see. The taboo hasn't disappeared so much as it's become selective, switching on or off depending on the setting.

Modern Everyday Examples: Where This Actually Matters

Wedding and Funeral Guestbooks

Writing a name in red pen in a Korean wedding guestbook, or on a cash gift envelope at either a wedding or a funeral, is something to avoid especially strongly. Writing a name in a color that evokes death at an auspicious event like a wedding runs directly against the spirit of the occasion. The same goes for funerals — it's extremely rare to see a guest's name written in red there either.

Birthday Cards and Congratulatory Cards

When writing a birthday card or a card congratulating someone on a graduation or promotion in Korea, writing the recipient's name in red pen isn't a good choice. No matter how warm the message itself is, the simple fact that the name is written in red can leave the recipient with a subtle sense of unease.

Office Documents and Work Memos

In Korean workplaces, red pens are typically used for corrections, edits, and flagging errors. A manager marking up corrections on a subordinate's report in red pen is a perfectly normal part of office life.

Using that same red pen to write someone's name, though, is read completely differently. Korean office workers generally treat black or blue pen as the default when writing name lists or formal letters that include a coworker's or manager's name.

Grading at School

It's common for Korean teachers to mark scores or incorrect answers in red pen when grading exams. Even so, there tends to be a separate reluctance to rewrite a student's own name in red. Grading marks and the act of writing someone's name are perceived as two distinct things.

Official Seals and Stamps Are a Different Matter Entirely

Here's a detail that often confuses foreign visitors once they learn about this taboo: traditional Korean name seals, called injang, are almost always stamped in red ink. These seals appear on contracts, bank documents, and official paperwork, and a bright red stamped name carries no negative connotation at all.

The difference comes down to what's actually happening. A stamped seal is a carved, formal mark of authority and identity, closer in spirit to a signature than to handwriting. It doesn't resemble the specific act of writing a living person's name by hand in red pen, so the death-registry association simply doesn't apply here.

A Softer Version in Digital Spaces

This taboo has carried over, at least partially, into digital spaces. Some Koreans say they feel a vague discomfort even seeing someone's name highlighted in red text in a messaging app or email.

That said, this digital version is much weaker than the version tied to handwriting on paper. Most Koreans don't think twice about highlighting a name in red in a work spreadsheet to flag a particular item.

Common Misunderstandings

• ❌ Myth: Red itself is considered an unlucky or negative color in Korean culture.
• ⭕ Reality: Red is actually tied to vitality and good fortune in traditional Korean thought — it's the specific pairing of red ink with a person's name that carries the taboo, not the color alone.
• ❌ Myth: All Koreans today take this taboo seriously and actively avoid red pens.
• ⭕ Reality: Awareness has faded sharply among Koreans in their twenties and thirties, who mostly ignore it in casual settings but still switch it back on for weddings, funerals, or around older relatives.
• ❌ Myth: Using a red pen to mark corrections on a document is also disrespectful.
• ⭕ Reality: The taboo applies specifically to writing a name in red — correcting or flagging text in red ink is completely normal in Korean offices and schools.

What Koreans Actually Say

The lines below aren't direct quotes from real interviews — they're representative of the kind of language Koreans commonly use in these situations.

Foreigner: "Why did you look so uncomfortable when I wrote your name in red pen?" Korean: "It's an old thing about death registries. I don't really believe it, but seeing it still feels weird." (thinking: I couldn't even explain why it bothered me that much.)

Foreigner: "Do young Koreans still care about this?" Korean: "Honestly, not really day to day. But if it's a wedding guestbook, I'd never use red — my mom would notice immediately."

Foreigner: "So is red pen fine for grading papers?" Korean: "Totally fine. It's just writing an actual name in red that feels off."

Practical Tips for Foreign Visitors

Default to Black or Blue for Names

When a foreign visitor needs to write a card, fill out a document, or sign a guestbook in Korea, defaulting to a black or blue pen is the safest choice. Neither color carries any negative association, and both are accepted without issue in any situation.

Be Especially Careful at Weddings and Funerals

If a foreign visitor needs to write a name in a Korean wedding guestbook or on a cash gift envelope, a red pen should be avoided without exception. This taboo is at its most sensitive at these kinds of formal occasions.

Corrections and Edits Are Completely Fine

There's no issue at all with using a red pen to mark errors or leave comments while reviewing a document at a Korean workplace or school. This taboo is specific to "writing a name" — it doesn't apply to every use of a red pen.

Don't Overthink an Honest Mistake

If a foreign visitor accidentally writes someone's name in red pen without knowing about this taboo, it almost never causes any real, lasting damage to the relationship. Most Koreans naturally understand that a foreign visitor likely wasn't aware of the cultural background.

Once a foreign visitor knows about this, though, consciously choosing a pen color going forward can leave a genuinely good impression on Korean coworkers or friends.

Digital Documents Are Much Lower-Stakes

A foreign visitor doesn't need to worry much about highlighting a name in red text in a digital document like Excel or Word. This taboo is strongest in situations involving handwriting an actual name by hand, particularly in personal, formal contexts like cards or guestbooks.

Conclusion: A Single Color Marking the Line Between Life and Death

Korea's reluctance to write a name in red ink isn't simple superstition. It's an emotional remnant of an old funeral custom that once drew a clear line between the living and the dead, and that line has survived into the present day.

Red itself isn't treated as a negative color in Korean culture. If anything, it also symbolizes vitality and good fortune. But when that red is paired with the very specific target of a person's name, it starts to echo the registries once kept for the deceased.

How strongly this matters today depends on who you're writing for and where. Among Korea's older generations, the discomfort is immediate and instinctive. Among Koreans in their twenties and thirties, it's faded into something closer to background noise — mostly irrelevant in casual life, but still quietly switched back on the moment a wedding, a funeral, or a parent's eyes enter the picture.

When a foreign visitor needs to write someone's name in Korea, the small habit of reaching for a black or blue pen instead is enough to show real respect for a boundary Korean society has carried forward for a very long time.
