Starbucks
Starbucks's identity has been carried by the canonical Siren mark and House Green since the brand's 1971 founding. The chassis stays warm — cream-paper canvas evoking the recycled paper cups, deep house-green ink, the Siren-mark green reserved for interactive moments — so a single muted green can do brand work across decades of store-counter consistency. Alongside the year-round register, the catalog reads the seasonal Q4 holiday-cup surface that has shipped festive red since the late 1990s.
Siren Green
The store-counter year-round register: cream-paper canvas evoking the warm-recycled paper cups, House Green as the dominant ink, the Starbucks Siren-mark green as the chassis interactive accent. The atmosphere reads the canonical year-round Starbucks identity — calm cream restraint, the canonical brand green carrying brand-mark moments, type rhythm tuned for menu and product readability. A study in how a global coffee brand can carry warmth through chassis restraint and a single muted green that has held identical for decades.

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.

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

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

Heading scale
Six levels, each picking up the brand's weight, tracking, and transform tokens.
h1 — Starbucks
h2 — Siren Green
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).

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-primaryenergy-secondarySurfaces
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-canvasbg-sunkbg-spotlightbg-surfaceSignal — Text hierarchy
Three emphasis levels for information hierarchy.
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).

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.

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

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.
