Colors in Korean: Every Color + How Adjectives Work
You know the word for "red." Then a friend points at an apple and you freeze — is it 빨간색 or 빨간? Both mean red, and picking the wrong one is a slip almost every beginner makes. This is a beginner-friendly guide to the colors in Korean, plus the small rule that decides which form you actually say.
What are the colors in Korean?
Most everyday colors in Korean end in 색 (saek), which literally means "color." So 빨간색 is "red (color)," 파란색 is "blue," 노란색 is "yellow." That 색 form is the noun — the answer to "what color is it?" You reach for it whenever the color stands on its own.
| Color (색 form) | Romanization | English | Before a noun |
|---|---|---|---|
| 빨간색 | ppalgansaek | red | 빨간 (ppalgan) |
| 파란색 | paransaek | blue | 파란 (paran) |
| 노란색 | noransaek | yellow | 노란 (noran) |
| 초록색 | choroksaek | green | 초록색 (choroksaek) |
| 하얀색 | hayansaek | white | 하얀 (hayan) |
| 까만색 | kkamansaek | black | 까만 (kkaman) |
| 분홍색 | bunhongsaek | pink | 분홍색 (bunhongsaek) |
Hear each color spoken
Tap each word to hear a native speaker. Notice the tense first sounds in 빨간색 and 까만색 — that little catch in the throat is the double consonant.
One question puts all of these to work: 무슨 색이에요? (museun saegieyo?) — "What color is it?" Answer with the 색 form plus 이에요: 빨간색이에요 (it's red), 파란색이에요 (it's blue). One question, seven ready-made answers.
How Korean adjectives work: the -(으)ㄴ rule
Here's the part textbooks bury. Korean adjectives are really descriptive verbs — 크다 means "to be big," 작다 means "to be small." To put one in front of a noun, you swap the dictionary -다 for -(으)ㄴ. So 크다 becomes 큰, and "a big house" is 큰 집.
The choice between ㄴ and 은 depends on one thing: the last sound of the stem. Vowel-ending stems take just ㄴ. Consonant-ending stems take 은. That's the whole rule.
| Dictionary form | Stem ends in | Add | Before a noun |
|---|---|---|---|
| 크다 (keuda, to be big) | vowel (크) | ㄴ | 큰 (keun) — 큰 집, a big house |
| 예쁘다 (yeppeuda, to be pretty) | vowel (쁘) | ㄴ | 예쁜 (yeppeun) — 예쁜 꽃, a pretty flower |
| 작다 (jakda, to be small) | consonant (작) | 은 | 작은 (jageun) — 작은 가방, a small bag |
| 좋다 (jota, to be good) | consonant (좋) | 은 | 좋은 (joeun) — 좋은 사람, a good person |
The colors follow the same idea, they just hide it. Play these five and listen for how the adjective locks onto the noun — no pause, one smooth phrase.
Color adjectives like 빨갛다, 파랗다, 노랗다, 하얗다, 까맣다 are irregular — the ㅎ quietly drops, giving 빨간, 파란, 노란, 하얀, 까만. Don't build them from the rule; just memorize the short forms. And 초록 (green) and 분홍 (pink) are plain nouns, so they keep 색: 초록색 우산 (a green umbrella).

Common mistakes with colors in Korean
| Mistake | Correct | Why |
|---|---|---|
| 크은 집 (keu-eun jip) | 큰 집 (keun jip) | 크다's stem 크 ends in a vowel, so add only ㄴ. Only consonant-ending stems take 은. |
| 빨강 사과 (ppalgang sagwa) | 빨간 사과 (ppalgan sagwa) | 빨강 is the noun "red." Before a noun you need the adjective form 빨간 (or 빨간색). |
| 사과가 빨간. | 사과가 빨개요. (ppalgaeyo) | 빨간 only works in front of a noun. To end a sentence, use 빨개요 or 빨간색이에요. |
Colors in Korean — Quick Check
1. How do you say "a blue sky" (blue right before the noun)?
2. 작다 (to be small) goes in front of a noun. What form do you use?
3. Which sentence correctly says "The apple is red"?
So the colors in Korean come down to two shapes. Standing alone, use the 색 form: 빨간색, 파란색. Sitting in front of a noun, drop to the short adjective and follow the -(으)ㄴ rule: 빨간 사과, 큰 집.
Now try it: colors in Korean stick fastest when you say them, so name three things around you by color — 빨간 컵, 파란 책, 하얀 벽. Then drill the color words with audio, watch the same -(으)ㄴ logic drive Korean verb conjugation, or pair colors with this and that to point and describe.
