Japanese Colors: Complete Vocabulary Guide with Kanji
Japanese colors have a fascinating grammar distinction that trips up almost every learner: some colors are い-adjectives and can modify nouns directly, while others require the particle の. Getting this wrong produces sentences that sound unnatural to native ears. This guide covers all the basic and traditional colors, the adjective rule, and how to use colors in natural Japanese sentences.
Basic Japanese Colors
The 10 basic colors every learner needs, with their adjective forms and examples:
| Kanji | Reading | Romaji | Meaning | Adjective form | Example |
|---|---|---|---|---|---|
| 赤 | あか | aka | Red | 赤い (akai) | 赤い車 (red car) |
| 青 | あお | ao | Blue / Blue-green | 青い (aoi) | 青い空 (blue sky) |
| 黄色 | きいろ | kiiro | Yellow | 黄色い (kiiroi) | 黄色い花 (yellow flower) |
| 緑 | みどり | midori | Green | 緑の (midori no) | 緑のシャツ (green shirt) |
| 白 | しろ | shiro | White | 白い (shiroi) | 白い雪 (white snow) |
| 黒 | くろ | kuro | Black | 黒い (kuroi) | 黒い猫 (black cat) |
| 茶色 | ちゃいろ | chairo | Brown | 茶色の (chairo no) | 茶色の犬 (brown dog) |
| 紫 | むらさき | murasaki | Purple | 紫の (murasaki no) | 紫の花 (purple flower) |
| 橙 | だいだい | daidai | Orange | オレンジの (orenji no) | オレンジのジュース |
| ピンク | ぴんく | pinku | Pink | ピンクの (pinku no) | ピンクのドレス (pink dress) |
The Grammar Rule: い-Adjective Colors vs の-Form Colors
This is the most important grammar rule for Japanese colors. Only 5 colors are true い-adjectives — the rest use の to modify nouns.
The 5 い-adjective colors
These colors conjugate like い-adjectives: 赤い (akai), 青い (aoi), 白い (shiroi), 黒い (kuroi), 黄色い (kiiroi).
Colors that use の
緑, 茶色, 紫, オレンジ, ピンク — and all other colors — use の to modify nouns. They also use ～色 (iro, color) suffix in some constructions.
Using colors in predicates
When a color is the predicate (X is Y), い-adjectives drop the の, and の-form colors use です or だ.
The Blue-Green Ambiguity: 青 vs 緑
Japanese historically did not distinguish clearly between blue and green — both were covered by 青 (ao). This legacy persists in modern Japanese in surprising ways:
- 青信号 (aoshingou) — "blue traffic light" even though the light is clearly green by Western standards.
- 青葉 (aoba) — "green leaves" (not 緑葉). Young green vegetation uses 青, not 緑.
- 青い野菜 — green vegetables are described as 青い (aoi), not 緑い (midori-i, which doesn't exist).
- 顔が青い — "someone's face is pale/ashen" — uses 青, not 緑.
Traditional Japanese Colors (伝統色)
Japan has an extraordinarily rich vocabulary of traditional color names, many dating to the Heian period (794–1185). These colors were central to the layered kimono system (kasane no irome) where court nobles expressed their rank and taste through color combinations.
朱しゅ (shu)Vermillion
The deep orange-red of lacquerware and shrine gates (鳥居). The color of protection and vitality in Japanese culture.
藍あい (ai)Indigo
Deep blue-purple made from the indigo plant. Used extensively in traditional textiles and kimono. "Japan blue" in Western observation.
桜色さくらいろ (sakura-iro)Sakura pink
The pale pink of cherry blossoms — lighter and softer than Western pink. Synonymous with spring and transience.
紺こん (kon)Navy blue
Deep dark blue, commonly used in school uniforms, work wear, and formal kimono. Considered reliable and dignified.
紅くれない (kurenai)Deep crimson
The deep red extracted from safflower (紅花). The traditional red of women's undergarments in the Heian period.
鶸色ひわいろ (hiwa-iro)Yellow-green
The fresh yellow-green of a siskin bird's plumage. A color of spring foliage popular in Heian court clothing.
瑠璃色るりいろ (ruri-iro)Lapis blue
The deep blue of lapis lazuli. Used in Buddhist art and considered sacred in Japanese aesthetics.
萌黄もえぎ (moegi)Fresh green
The vivid yellow-green of new spring growth. One of the most beloved traditional colors for its association with renewal.

How do you say the colors in Japanese?
The basic Japanese colors are: 赤 (aka, red), 青 (ao, blue), 黄色 (kiiro, yellow), 緑 (midori, green), 白 (shiro, white), 黒 (kuro, black), 茶色 (chairo, brown), 紫 (murasaki, purple), 橙 (daidai, orange), and ピンク (pinku, pink). Some colors have both a native Japanese word and a loanword from English (like ピンク and 桃色/momoiro for pink).
Which Japanese colors are い-adjectives?
The colors that are true い-adjectives (and can modify nouns directly with い) are: 赤い (akai, red), 青い (aoi, blue), 白い (shiroi, white), 黒い (kuroi, black), and 黄色い (kiiroi, yellow). These five can say "red car" = 赤い車. Other colors like 緑, 茶色, 紫 use の to modify nouns: 緑の車, 茶色の車.
What is the difference between 青 and 緑 in Japanese?
This is a fascinating feature of Japanese colour perception. 青 (ao) historically covered both blue and green. Even today, traffic lights use 青信号 (ao shingou, blue signal) even though the light appears green. Fresh vegetables and unripe fruit use 青い (aoi). 緑 (midori) is the modern word for green used in most contemporary contexts. The line between them is blurry — 青葉 (aoba, green leaves) uses 青, but 緑の葉 is also natural.
What are traditional Japanese colors?
Traditional Japanese colors (伝統色) are a rich system of named colors developed in the Heian period. They include: 朱 (shu, vermillion), 藍 (ai, indigo), 桜色 (sakura-iro, cherry blossom pink), 鶸色 (hiwa-iro, yellow-green like a finch), 瑠璃色 (ruri-iro, lapis lazuli blue), 紺 (kon, navy blue), and 紅 (kurenai, deep crimson). Each color was used in specific contexts in courtly life.
