National Geographic

National Geographic's yellow rectangle has carried the brand since 1888, which makes the explorer's border one of the longest-lived continuous publication identities in commercial design. The chassis around that rectangle has always been deliberately spare — full-bleed photography carrying the editorial work, restrained typography deferring to the image, the single saturated yellow doing the brand work where lesser publications would reach for three colors.

Magazine Edition

The explorer's-yellow magazine register: cream-paper canvas evoking the editorial spread, AA-darkened amber as the engineering-primary signal, canonical Pantone-116 yellow retained as the decorative secondary the brand-bug requires. The yellow rectangle has carried National Geographic identity since 1888, and the atmosphere reads that discipline through chrome: zero radii to preserve the rectangle-bug, neutral tracking on heading, heavy display weights for the cover banner, editorial serif keeping long-form prose primary. A study in how a scientific publication makes a single rectangle into the most-recognized identity in print.

Live preview

A believable product moment rendered against the active atmosphere. Hover, focus, and toggle the controls — typography weight, button tracking, corner radii, and motion timing all carry the brand's identity.

Typography

Headings, body, and signal text rendered against the active atmosphere.

Typefaces

The active heading and body families — brand override first, atmosphere default second.

Heading · --font-heading

Body · --font-body

Lora

Heading scale

Six levels, each picking up the brand's weight, tracking, and transform tokens.

h1 — National Geographic

h2 — Magazine Edition

h3 — Subsection

h4 — Section header

h5 — Subheading
h6 — Minor subheading
Body & secondary text

Standard reading copy and supporting metadata.

Paragraph — body typography, dim color. Standard readable text for descriptions and content.

Small — small typography, mute color. Used for captions and metadata.

Caption — caption level utility class.

Brand overrides

Beyond the typeface, brand profiles can tune weight, tracking, and text-transform per role. Display covers h1/h2, Heading covers h3/h4, Body covers paragraphs and small text, Button covers all .btn-* labels. Anything not declared inherits from the atmosphere's defaults.

Supported overrides & this brand's values

A brand profile can override 4 weights, 4 trackings, and 3 transforms (Body has no transform — prose never gets uppercased).

  • Display weight (h1, h2) · --weight-display 800
  • Display tracking (h1, h2) · --tracking-display 0
  • Display transform (h1, h2) · --text-transform-display …

Palette & shape

The color palette, corner geometry, and motion curves under the active atmosphere. Atmospheres change the values; the architecture never moves.

Energy — Brand axis

The two colors that change most per atmosphere. Primary drives CTAs, focus rings, and headings. Secondary tints hovers, press feedback, toggle thumbs, and the selected channel in the live preview above.

energy-primary
energy-secondary
Surfaces

Background layers from the depth model. Canvas is the floor — sunk and spotlight are its recess and ambient variants. Surface is where floating elements live. Every tile carries --border-color at var(--physics-border-width), so the border tier is visible on each outline.

bg-canvas
bg-sunk
bg-spotlight
bg-surface
Signal — Text hierarchy

Three emphasis levels for information hierarchy.

Main Dim Mute
Color extensions

Two additional palettes layered on top of the five-layer system. Neither is a brand-axis variable, so they don't change much per atmosphere.

Semantic — success, error, premium, and system carry the same meaning on every brand. Most brands inherit the defaults; the rare override applies when a brand's primary hue would clash (e.g. a green primary forces a different success green).

Success

Positive outcome

Error

Destructive, failure

Premium

Attention, cost

System

Informational

Data palette — 8 categorical slots derived from primary

Hue-rotated 45° per step from --energy-primary in OKLCH. Cool atmospheres yield cool-leaning palettes; warm yield warm-leaning. Use for chart series, chips, tags, kanban columns, avatar fallbacks, and calendar categories — anywhere unrelated-by-severity data needs distinct identity. Not for severity (data-3 means "third slot," not "success"). Auto-contrast handles text color on any bg-data-* tile.

Radii — corner geometry

All five radius levels, rendered with the active atmosphere's tokens. Brand-overridden values are emphasized.

--radius-sm 0
--radius-md 0
--radius-lg 0
--radius-xl 0
--radius-full …
Motion

Brand profiles can also override the system's speeds and easing curves. The square below uses --speed-slow and --ease-spring-snappy — both carried by the brand axis when set, otherwise inherited from the active physics preset. Hover the demo to play.

Supported overrides & this brand's values

A brand profile can override 3 speed levels and 4 easing curves. Anything not declared inherits from the active physics preset (glass / flat / retro). Cascade delays (--delay-cascade, --delay-sequence) are physics-only and not part of the brand axis.

  • Fast · --speed-fast …
  • Base · --speed-base …
