Overview

Visual Theme & Atmosphere

CrowdWorks is Japan's large crowdsourcing marketplace — clients post work, freelancers bid on it. The landing surface is white, dense and set mostly at 12px (190 elements), with a saturated orange #f26731 reserved for the actions that start an account and a navy #004980 that is — by a wide margin — the most-rendered colour on the page.

That navy is --text-color-link, not the body ink. It paints 138 elements because a marketplace home is mostly links to categories and jobs. The body ink is --text-color-black, #353d48, a blue-leaning charcoal.

Three things make the token set worth reading:

  • 32 tokens are whole CSS font shorthands. --paragraph-m-w3 is 400 18px / 1.8 "Hiragino Kaku Gothic Pro", sans-serif — weight, size, line height and family in one value. No other reference in this catalog tokenises typography this way.
  • 91 z-index tokens are named for the element they stack, down to --z-jobs-sidebar-category-list-right-arrow, and written as arithmetic — calc(calc(1799 + 1) + 50) for a modal dialog.
  • 56 tokens belong to AI CrowdWorks, a sub-brand with its own purple-and-teal system, kept in its own namespace inside the parent's sheet.

Primary tasks

  • Start as a client or a freelancer; sign in, or sign up with Google.
  • Browse job categories, which is what most of the page is.

Brand Narrative

CrowdWorks connects clients and freelancers across Japan, and the landing page is built as a directory into that marketplace: most of it is links, which is why the link navy outnumbers every other colour. The orange appears only where an account begins.

The token set is the work of a team with a large, long-lived product to keep consistent — every stacking layer named after the thing it stacks, typography packaged as ready-to-use declarations, and a newer AI product given its own colour system without being allowed to leak into the parent's.

Principles

  • Package the decision. A font token is a whole font declaration.
  • Name layers by their occupant. --z-jobs-sidebar-category-list-right-arrow.
  • Contain the sub-brand. AI CrowdWorks lives in --aicw-*.

Personas

Not researched. No persona claim is made from a UI capture.

Colors

Measured with getComputedStyle on crowdworks.jp. 412 custom properties resolve; 17 are Font Awesome's — --fa-font-light is normal 300 1em/1 "Font Awesome 6 Pro" and the rest are the same icon font — and are excluded. CrowdWorks owns the other 395.

Primary blue

  • Primary (#006ab6) — --primary-800, and also --surface-color-primary, --text-color-primary, --line-color-primary and --object-color-primary. One value under four semantic names, one per family.
  • Primary 500 (#239ae7) · Primary 50 (#e3f2fb) — the middle and pale ends of a ten-step ramp.
  • Link (#004980) — --text-color-link, which is --blue-900. The most-rendered colour on the page.

Orange — the account actions

  • Brand CTA (#f26731) — --orange-400, the fill on both sign-up buttons.
  • Orange 500 (#f0510f) · Orange 700 (#d54507) · Text Orange (#cc4900, --text-color-orange = --orange-800).

Ink and lines

  • Foreground (#353d48) — --text-color-black = --gray-800.
  • Text Gray (#617084) — --text-color-gray = --gray-500.
  • Disabled (#cfd4da) — --text-color-disabled, and also --line-color-gray-light.
  • Line Gray (#afb7c1) — --line-color-gray = --gray-200, and the border on the login button.

Surfaces

Canvas (#ffffff) · Surface Gray Light (#ecedf0) · Surface Gray Bright (#f9fafb) · Surface Blue Light (#e7f1fa) · Surface Blue Bright (#f5f9ff).

Status — each with a light surface

Accent (#cb2442) · Danger (#c92b36) on #feecf0 · Success (#177835) on #e6f4e9 · Warning (#8f6c00) on #fef9e4 · Info (#0467a2) on #e0f2fa. Every one of those strong values is the -800 or -900 step of its ramp.

Visited (#9c27b0) — --text-color-visited, which is Material Design's purple 500.

The ramps, and one that is Material's

Eleven ramps: primary blue bluegray green red orange yellow accent purple gray, ten steps each, plus black and white as alpha ladders (rgb(0 0 0 / 5%) through / 90%).

--purple-* is Material Design's purple palette — #9c27b0, #ab47bc, #ba68c8, #ce93d8, #e1bee7, #f3e5f5 — with one exception: --purple-600 is #8d24aa where Material has #8e24aa. The AI sub-brand's own --aicw-purple-600 is #8e24aa. Recorded as found; which was copied from which is not knowable from the page.

AI CrowdWorks — a sub-brand in its own namespace

AICW Primary (#5628a8) — --aicw-primary-purple and --aicw-surface-color-primary · AICW Primary Dark (#4b2485) — its text colour · AICW Secondary (#0a7093) — a teal, also its link colour · AICW Tertiary (#32d4af) — a mint.

It publishes five gradients built only from those, e.g. --aicw-gradient-primary-tertiary: linear-gradient(90deg, #5628a8, #32d4af). It is unmistakably CrowdWorks' own: --z-aicw-projects-login-gate-overlay puts it inside the parent's z-index namespace.

Typography

Font family

Noto Sans JP is the rendered face — the only loaded webfont, and the first family on 308 text elements. --font-family-base declares "Hiragino Kaku Gothic Pro", sans-serif, which is an operating-system face; it renders on 54 elements, all of them set through the --paragraph-* / --single-* tokens that carry it inside their value. It is not recorded as a brand face.

Typography as whole shorthands

This is the distinctive part. Two families, 16 tokens each:

--paragraph-<size>-w<3|6>   400|700  <size> / 1.8  "Hiragino Kaku Gothic Pro", sans-serif
--single-<size>-w<3|6>      400|700  <size> / 1    "Hiragino Kaku Gothic Pro", sans-serif

paragraph is running text at a 1.8 line height; single is one line at 1. w3 is weight 400, w6 is 700. Sizes run xxxs 10 · xxs 12 · xs 14 · s 16 · m 18 · l 22 · xl 28 · xxl 37. A consumer takes one token and gets a complete font declaration.

The size scale beneath adds 56 and 112 for display use.

Rendered: 12px ×190 · 14px ×67 · 16px ×37 · 20px ×18 · 18px ×15 · 24px ×13 · 28px ×10. Weights 400 ×217 and 700 ×143.

Values kept in prose

Measured values the DESIGN.md token grammar cannot carry, kept verbatim:

  • typography.leading.single: 1
  • typography.leading.paragraph: 1.8

Layout

  • Name the element, not the layer. 91 z-index tokens, each for one specific component.
  • One token, one complete font declaration.
  • A sub-brand is a namespace, not a theme — --aicw-* beside the parent, not replacing it.

Responsive Behavior

Not measured. Desktop 1440×1000 only.

Elevation & Depth

Nine shadow tokens, all centred (no offset), in three composed sizes: --shadow-s 0 0 2px 0 rgb(0 0 0 / 30%), 0 0 3px 1px rgb(0 0 0 / 15%) · --shadow-m 0 0 3px 0 … 30%, 0 0 8px 3px … 15% · --shadow-l 0 0 4px 0 … 30%, 0 0 12px 6px … 15% — a tight core plus a soft halo.

The one shadow observed on a control, on the Google button, is not any of these: it is offset -1px 2px and tinted grey. It comes from the Google sign-in component rather than the token set.

--blur-3 is blur(3px), and --background-color-black-modal is rgb(0 0 0 / 20%).

Motion & Easing

No motion token exists among the 395, and every measured control computes transition: all with no duration — so the hover changes happen instantly.

Tier 1 sources: https://crowdworks.jp/ (live marketplace surface — 412 custom properties read via getComputedStyle, 17 of them Font Awesome's and excluded; six controls measured at rest, hover, pressed and focus, captured 2026-09-22); https://crowdworks.jp/zz-this-does-not-exist (nonsense-path control — a real HTTP 404 titled 「ページが見つかりませんでした【クラウドワークス】」 with its own 664-character body, establishing the host is not a catch-all, captured 2026-09-22)

Components

Six controls measured, every state on its own page load, focus read for every control before the mouse moved.

Hover is a translucent layer

The buttons keep their fill colour on hover and lay a black gradient over it in background-image: 10% on the two orange sign-up buttons, 5% on the white login and Google buttons. (Measured 2026-09-26; the first capture on 2026-09-22 read these as "no change" because the probe compared background colour but not background image.) The guide row, はじめての方へ, washes its background to rgba(32,34,39,.05) — ink at 5%. The email field is the one control that stays identical under the pointer.

  • Wide CTA — #f26731, white 16px/700, 4px radius, 312×48.
  • Header sign-up — the same orange, 14px/700, 130×40.
  • Login — #ffffff, #353d48 label, 1px solid #afb7c1, 89×40.
  • Google — #ffffff with a 1px solid #d6d6d6 border and the only shadow among the six, rgba(163,162,162,0.2) -1px 2px 4px — cast down and to the left.
  • Guide row — #f7f9fa fill, #000000 label at 11px/700, a 1px solid #ecedf0 top rule only, 360×53.
  • Email field — #ffffff, 1px solid #bcc5cc, 4px radius, 291×45.

Focus is the browser's — at three different widths

Every focusable button renders outline: rgb(0, 95, 204) auto — Chrome's default ring — but at 1px, 2px or 3px depending on the control. The style stays auto, so it is still the browser's ring; what CrowdWorks sets is only the width. --space-outline-offset-focus: 3px sits in the spacing scale beside it. No focus colour is recorded.

The email field shows no focus indicator at all. It matches :focus-visible and every property is unchanged — no ring, no border change, no shadow.

Radius

--border-radius-2 · -4 · -8 · -16 · -24 · -32 · -10000. Rendered: 4px ×32 · 8px ×18 · 10px ×7 · 10000px ×3. The pill is ten thousand pixels.

States

Six components, every state measured. Hover and press lay a black layer over the buttons — 10% on orange, 5% on white; the guide row washes to ink at 5%; the email field does not change. Focus is the browser's auto ring at a per-control width on every button, and nothing at all on the email field.

No disabled state was observed on a rendered control. --text-color-disabled #cfd4da exists in the set.

Live state probe, 2026-10-16 (https://crowdworks.jp/), button-cta: focus — background-image linear-gradient(rgba(0, 0, 0, 0.1), rgba(0, 0, 0, 0.1)), browser default focus ring (outline auto).

Do's and Don'ts

Do

  • Take a whole --paragraph-* or --single-* token for a text style rather than rebuilding it from size, weight and line height.
  • Use #004980 for links and #353d48 for body text — the navy is the link, not the ink.
  • Keep AI CrowdWorks surfaces in the --aicw-* namespace.

Don't

  • Don't count --fa-* as CrowdWorks' — it is Font Awesome.
  • Don't take the Google button's offset shadow as a CrowdWorks elevation token.
  • Don't copy the email field's missing focus indicator.

Voice & Tone

Not assessed as authored voice. 5,686 characters on the measured surface, mostly category and job-listing links.
