Microsoft

Calm by default, unmistakable in the details. Microsoft keeps the page quiet (white and ice grounds, plain sentence-case Segoe, one blue) so the four-square logo, product photos and rounded Fluent shapes carry the recognition. Our reading

  • The four-square logo with the gray Segoe logotype

  • Plain, second-person writing

The one thing that varies

From product UI (Fluent tokens: 4px radius, 32px buttons, #0F6CBD) to marketing pages (24px-radius cards, 40px buttons, #0078D4, gradient grounds): the same type, color logic and voice at different softness.

Our engine's setting, built from their rules.

Every piece passes 3 checks

Logo hidden

Cover the logo. Segoe-like type in sentence case, soft white cards, navy text and one blue should still read as Microsoft.

Contrast check

Every text pairing meets 4.5:1 (3:1 for large text), and color never carries meaning alone.

Trademark check

No Microsoft name used as a verb, noun or pun, and nothing implies endorsement.

Strategy

One Microsoft across every device: products, AI and stories presented in one calm, familiar system (our reading of the Fluent principles and the homepage). Our reading

Proof behind each pillar

Story Published

Microsoft redrew its logo in 2012, the first change in 25 years: a four-square symbol and a Segoe logotype meant to move across PCs, phones, tablets and TVs (paraphrase of the launch post). Fluent 2 is the design system that carries that one look across Windows, web, iOS and Android today.

Values

Natural on every platform

Adapt to the device and build on what people already know; reuse native patterns most of the time (paraphrase).

Published
Built for focus

Keep people in flow; less visual clutter keeps them calm and confident (paraphrase).

Published
One for all, all for one

Include a range of abilities and perspectives early; everyone should feel they belong (paraphrase).

Published
Unmistakably Microsoft

Signature experiences in color, sound, illustration and icons make products feel like one Microsoft (paraphrase).

Published

Category. Software, cloud, devices and AI for people and organizations (paraphrase of the homepage nav: Microsoft 365, Azure, Copilot, Windows, Surface, Xbox). Observed

Why them

  1. One integrated family: Windows, Surface, Xbox, Microsoft 365 and Copilot sold and explained in one place. Observed
  2. AI framed through real-world impact stories rather than feature lists. Observed

Instead of

Unnamed: microsoft.com names no competitors.

Boilerplate Published

Microsoft's mission is to empower every person and every organization on the planet to achieve more (quoted from the About page).

Taglines

Unmistakably Microsoft Published

They never claim

  • Offers carry their footnote markers (* and **) and legal detail; never state a price without its qualifier ('Save up to', 'on select'). Observed
  • Third parties may state compatibility truthfully but must not imply affiliation or endorsement. Published

Find your next PC

Do Plain, verb first, second person implied.

Click here to Excel at productivity!

Don’t 'Click here', a product-name pun and an exclamation point.

Plain sentence-case text is easier to read and to localize (Fluent says so for capitalization).

Full spec
  • Sentence case headlines
  • Keep it simple: plain language, short sentences and fragments
  • Get to the point fast; prune every excess word
  • Talk like a person: informal and conversational, one-on-one
  • Second person (you, your); avoid first person unless writing as the reader
  • Present tense and active voice
  • No periods in headers, buttons, labels or bullet lists; avoid exclamation points
  • Short, descriptive link text; never 'Click here'
  • No directional words (above, below, left, right)
  • Don't use all caps for attention
  • Use Microsoft product names as adjectives before nouns ('Excel spreadsheets'), never as verbs or nouns
  • No puns or slogans built from Microsoft names

PlainFriendlyHelpful

Fluent's content design asks for plain, conversational, second-person writing in sentence case, present tense and active voice, with sparse punctuation and no exclamation points. The homepage is warmer ('Hi there') but just as plain.

  • Keep it simple; get to the point fast; talk like a person
  • Second person; present tense; active voice
  • No periods in headers, buttons or labels; no exclamation points
  • Descriptive link text, never 'Click here'
  • Two voices, scoped. Fluent 2's content-design voice is for product UI: simple, get to the point, talk like a person, second person, present tense, active voice, sentence case.
  • The microsoft.com homepage is a store-and-stories voice: a warm greeting H1 ('Hi there, welcome to Microsoft'), product names with plain offers ('Save up to $100.00 on select Surface Pro'), and story headlines that pair a situation with what AI does ('When disaster strikes, HASTE can help').
  • A landing page follows the homepage voice: a short sentence-case headline, one or two plain sentences, and a 2-3 word verb-first button ('Shop now', 'Learn more', 'Read the story').
  • Use 'you'; avoid 'I', 'we' and 'Microsoft' as the subject unless the sentence needs it (Fluent: use passive voice only to avoid saying 'we' or 'Microsoft').

Don’t Fluent: avoid brand color on large surfaces.

Lighter neutrals focus attention; keeping blue for actions makes the next step obvious.

Full spec
  • Neutrals ground the interface; lighter surfaces mark the area of focus
  • Brand color for actions and selected states, never large surfaces
  • Semantic colors only for status, never decoration
  • Controls darken from rest to hover to pressed; focus adds a thicker stroke
  • Text contrast 4.5:1 (3:1 for large text); never color alone
  • Don’t flood a band with brand blue
  • Don’t use red, yellow or green as decoration
  • Don’t use the logo's four colors as a UI palette
Action blue (site)#0078D4
Fluent brandWeb 80#0F6CBD
Headline ink#0E1726
Neutral foreground 1#242424 (grey 14)
Background 2#FAFAFA (grey 98)

Fluent defines three palettes: neutral (black, white, grays for surfaces and text), shared (for avatars, badges, calendars and status) and brand (product colors). Brand color is for prominence and anchoring, not large surfaces. microsoft.com runs on white cards, warm-white and ice gradient grounds, navy type and one action blue (#0078D4).

Not published: percentages or ratios of color use; a marketing palette separate from Fluent's UI tokens.

Literal, single-color outline icons stay recognizable and leave color to meaning.

Full spec
  • Regular theme for wayfinding and actions; filled for selected states
  • One solid color only
  • 12px icons inform, they don't take interaction
  • Modifiers filled, bottom right, only when needed
  • Scale product icons by factors of four from 48px
  • Don’t recolor product launch icons
  • Don’t use a product icon in place of the Microsoft logo
  • Don’t stack complex modifiers

Three collections: Fluent system icons (MIT-licensed, regular and filled themes), product launch icons (Microsoft apps) and file type icons. System icons are literal metaphors named for the object. microsoft.com uses 32px navy outline icons for quick links and 20-24px icons in controls.

Source: fluent2.microsoft.design/iconographymicrosoft.com/en-us

Illustration

Product-born art (Bloom) carries the brand into marketing without a separate drawing style.

Full spec
  • Use Microsoft's own product art (Bloom) or abstract light and color fields
  • Keep art inside rounded image frames
  • Don’t invent a cartoon or line-illustration style
  • Don’t build patterns from the logo squares

Fluent's public site names illustration as a signature experience but publishes no illustration guide. On microsoft.com, illustration appears as product art: the Windows 11 Bloom on device screens and abstract generated art for reports (the Digital Defense Report's blue glow and pixel grid).

Not published: an illustration style guide on the public Fluent site.

Source: fluent2.microsoft.design/design-principlesmicrosoft.com/en-us

Photography

Clean product shots sell; real people make AI concrete.

Full spec
  • Product shots: single device, soft light, plain ground, angled view
  • Stories: real people at work outdoors or on location, natural light
  • Crop to the frame's ratio: 3:4 promo, 16:9 story, 4:3 banner
  • Don’t use Microsoft photography in third-party work without permission (trademark guidelines)

Two kinds on the homepage: studio product photography (Surface, Xbox, accessories) on soft gray or dark grounds, and documentary photos of real people and places for AI stories (disaster response, supply chain, datacenter landscapes). Always in rounded frames.

Not published: a public photography guide.
