These twenty colours anchor most cultural references and palette discussions in Japanese design tradition. Each entry summarises the colour's pigment origin, historical use, and modern register in 80-150 words; click through to the full color dictionary for the complete /colors/[slug] detail page (palette uses, WCAG contrast, JSON API endpoint).

The Four Reds

Japanese tradition distinguishes four primary reds — each from a different pigment source, each carrying centuries of specific cultural use.

Kurenai

Kurenai (紅) is the deep crimson dyed from safflower petals (紅花, benibana) — one of the most labour-intensive colours in the entire Japanese tradition. Producing a single bolt of kurenai-dyed silk required pressing safflower petals through cold water, alkaline water, and acid in sequence; the yield was tiny. During the Heian period the colour was so expensive that laws periodically forbade commoners from wearing it.

Akane

Akane (茜) is the warmer, slightly orange-leaning red dyed from madder root (Rubia akane) — one of the oldest organic dyes used continuously in Japan. Archaeological evidence places its use back to the Yayoi period. Where kurenai is the crimson of the court, akane is the red of everyday cloth and folk textiles: kimonos for daughters, theatre costumes, traditional wedding accessories.

Shu

Shu (朱) is the bright orange-red of cinnabar pigment — mercury sulfide ground to powder and bound in lacquer. It's a mineral, not a dye, which gives it a luminous, almost glowing quality that no purely-red pigment can match. Shu is the colour of Shinto torii gates, temple pillars, ceremonial bowls, and the lacquerware traditions of Wajima and Kyoto.

鉛丹 Entan

Entan (鉛丹) is the heavier, slightly muted red made from lead tetroxide. It served historically as a ground for shu lacquer — entan would be applied first, and the more expensive shu cinnabar painted on top — but is also visible on its own in unrestored medieval temple architecture, where the shu top-coat has weathered away to reveal the entan beneath.

Wabi-Sabi Earth & Ink

The tea-room palette: warm earths, deep inks, and the cream anchor that holds them in tension.

Tobi

Tobi (鳶) takes its name from the Japanese black kite, the bird whose wing colour the dye-makers were trying to match. The result is a warm ink-brown — darker than chocolate, redder than sepia, with a particular rust undertone that reads as weathered rather than aged. It's a workhorse warm-axis colour: traditional craft objects, lacquerware bases, leather tones in Edo-period merchant clothing.

焦茶 Kogecha

Kogecha (焦茶) — literally 'burnt tea' — is the deep brown of over-brewed hojicha, of cedar weathered to near-black, of coffee grounds. It's a structural warm: the colour you place at the bottom of a composition to ground it, the trim colour around a wabi-sabi interior, the binding cloth on a hand-bound book.

Sumi

Sumi (墨) is the ink-black of pine soot or lamp soot mixed with hide glue and pressed into ink-sticks. Ground on a wet stone, it produces the calligraphy ink that has anchored Japanese visual culture for over a thousand years. Sumi is not 'black' in the Western sense — it has warmth, depth, and a slight sheen that pure pigment black lacks.

胡粉 Gofun

Gofun (胡粉) is the chalk-white pigment made from crushed and aged oyster shells. It's the white of Japanese-style folding screens, the priming layer beneath nihonga paintings, the bright base coat on Hina dolls. Unlike titanium white or zinc white in Western painting, gofun has tooth — a slight matte chalk quality that reads as material rather than as default 'white.'

Japandi Cool & Warm

The colours that bridge the Japanese and Scandinavian traditions: a pale cool axis (celadon, half-indigo) plus a controlled warm accent (persimmon, unbleached cream).

青磁 Seiji

Seiji (青磁) is the celadon green of the Chinese-influenced Korean and Japanese ceramic traditions. The name refers literally to the iron-glaze celadon ware — fired with a thin coat of iron-bearing slip that vitrifies into a pale grey-green. Centuries of tea-ceremony and incense-ceremony objects have established the colour as inseparable from quiet refinement.

Hanada

Hanada (縹) is the half-indigo blue — a cooler, paler blue than the deep koniro of Edo-period workwear, but warmer than pure cyan. It sits between sky-blue and a deep blue-grey. Historically it was used in court robes, summer kimonos, and shop curtains, and is one of the named colours that appears most consistently in Wada's catalogue.

Kaki

Kaki (柿) takes its name from the Japanese persimmon fruit — and refers specifically to the colour of a ripe persimmon, between burnt orange and warm terracotta. It's a saturated warm without the aggression of pure orange. Historically: Edo-period merchant signage, autumn kimonos, traditional pottery glazes.

生成 Kinari

Kinari (生成) — literally 'unbleached' or 'made-as-is' — is the colour of natural undyed silk, raw linen, and unbleached cotton. It's not white; it's the warmest of cream tones, with the tan undertone that fibres carry before bleaching. The word itself denotes the philosophical stance of leaving material in its natural state.

Imperial & Court

The Heian-era court colours that signal status, formality, and ceremony — including the kinjiki (forbidden) ranks.

Murasaki

Murasaki (紫) is the deep purple dyed from the roots of the murasaki plant (Lithospermum erythrorhizon) — a colour so labour-intensive to produce that the Heian court reserved its darkest variants as kinjiki (forbidden colours), wearable only by the imperial family and highest court ranks. The cheaper variants were available to the rest of the aristocracy; commoners were forbidden the colour entirely.

Full Murasaki page →

Kon

Kon (紺) is deep navy — the darkest practical shade of indigo, the colour of dyed-and-redyed-and-redyed cotton until the fibres are nearly black. Used historically for samurai under-armour (because the blue-black colour hides bloodstains), Edo-period merchant workwear, and the deep-night skies in classical wood-block prints. Kon reads weighty, grounded, and authoritative in a way pure black does not.

Indigo & Folk

The everyday-Japanese blues and greens of Edo-period workwear, folk textiles, and pre-modern craft tradition.

Ai

Ai (藍) is indigo — the deep blue dyed from the leaves of Polygonum tinctorium (Japanese indigo plant) through a fermented vat dye process that takes months to set up and decades to master. By the Edo period, ai was the workhorse blue of the entire country: samurai under-armour, merchant work clothes, futon covers, noren shop curtains. Whole towns built their economy around ai dyeing.

浅葱 Asagi

Asagi (浅葱) is the pale green-blue of young leek shoots — literally 'shallow leek' — and one of the named colours that appears most consistently across Wada's catalogue. It sits between sky-blue and pale celadon, with enough green to read as fresh rather than cool, and enough blue to read as bright rather than vegetal. Historically it was used for under-robes in summer kimonos and for low-rank samurai garments (specifically the Shinsengumi uniform haori in mid-19th century Kyoto).

瑠璃 Ruri

Ruri (瑠璃) is the vivid deep blue of lapis lazuli — the gemstone, not the dye. The colour is named after the stone, and the Buddhist Pure Land ('Eastern Lapis Realm') is where the pigment's cultural weight comes from. Where ai is everyday-blue, ruri is jewel-blue: saturated, slightly cool, and traditionally reserved for ceremonial textiles, religious paintings, and the most expensive lacquerware inlays.

常磐 Tokiwa

Tokiwa (常磐) — literally 'eternal rock' — is the deep evergreen of pine needles and cedar bark, named for the trees that hold their colour through winter. It's a structural green: the colour of an eternal hedge, a temple cypress, a household crest passed through generations. The word carries the connotation of permanence rather than nature.

Black, Yellow, and the Spring Palette

The remaining canonical hues that complete the working glossary: kuro (everyday black) and yamabuki (the kerria-flower spring gold).

Kuro

Kuro (黒) is black — but Japanese tradition distinguishes several blacks, and kuro is the everyday one: closer to Indian ink with a slight warmth, less absolute than printer's black. Used for kimono base colour in formal mourning (where it's worn paired with white only), for crests (mon) on white silk, and for the structural lines in calligraphy and ink-wash painting (sumi-e).

Full Kuro page →

山吹 Yamabuki

Yamabuki (山吹) is the saturated golden-yellow of the Japanese kerria flower — a bright spring-blooming shrub whose colour gave its name to one of the canonical Heian seasonal palettes. The colour reads sun-on-petals rather than citrus: it has the deep gold undertone that pure yellow lacks, and the soft warmth that prevents it from reading as institutional.
