roops巡

Every mark, color, type rule, and borrowed word that makes roops look like roops — the identity system, gathered on one page.

01 · The mark · 印

An ensō is a loop drawn with discipline.

The ensō (円相) — the zen circle, one breath, one stroke — is the rare logo concept that is not a metaphor. It literally is a loop. Left slightly open it is a run in progress; closed, a run complete.

Primary — the open ensō

Brush-weighted, imperfect, gap at the top right: the loop that will run again. The whole identity in one stroke.

巡

Seal — 巡 in vermillion

The hanko form for favicons, stamps, and small sizes. 巡: to make the rounds.

roops巡

Lockup — wordmark + seal

Lowercase serif wordmark, sealed like a signed document. The seal always sits last, as a signature does.

02 · Color · 色

Ink, paper, and one seal of vermillion.

Traditional Japanese color names (nihon no iro), each with a job. Vermillion is the only accent — it appears exactly where a hanko would: on things a human decided.

sumi · ink#1C1A17Text, marks, the ensō. Never pure black.
kinari · raw paper#F2EDE3The surface. Warm, faintly textured washi.
shu · vermillion#C73E2BThe seal. Alerts, acks, the one accent.
ai · indigo#2E4A5BSecondary ink — code, links, quiet emphasis.
koke · moss#6B7A5CHealthy status only. Moss grows on what is left in peace.
ōdo · ochre#A87A2AWarn status only. Bare earth shows where the moss has worn away.
nibi · dulled#8C8578Metadata, timestamps, the recessive layer.
03 · Type & rules · 型

Three faces, three jobs. Nothing improvised.

Every character on the page is set in one of three faces, and each face has exactly one job. Reaching for a fourth — or mixing the three — is what breaks the system.

04 · Working vocabulary · 語彙

Words the product borrows.

Not decoration — each term earns its place by naming something the harness already does. Used sparingly: one or two in the UI, the rest in docs and voice.

巡meguru / junto go around; a patrolA single firing of a loop. “Last 巡: 06:00.” CLI verb: roops rounds.
手入れteiretending, upkeepThe category of work Roops does — garden-keeping for repos and systems. The docs’ word for “maintenance loop.”
間mameaningful interval / negative spaceBoth meanings apply: the interval between runs, and the empty space of a healthy dashboard. One kanji, the whole product.
判hanthe seal / stampDispositions. To ack a finding is to stamp it. Hanko stamps as status iconography: 済 settled, 認 acknowledged, 休 snoozed — and 承 approved, the one stamp that becomes an order.
改善kaizencontinuous improvementThe philosophy of small recurring passes — the reason loops exist at all. Voice-of-brand word, not UI copy.

Ways to say it.

案 A
Quiet rounds. Kept promises.The bushidō read — dependability first.
案 B
The garden is raked every morning.The karesansui read — the README’s opening line.
案 C
Tend, don’t toil.The teire read — shortest, best on a terminal banner.
案 D
毎朝、庭を整える。“Each morning, the garden is set in order.” — for the people who will ask what it means. That is the point of a tagline.
