Superhuman, in one page

Superhumon's marketing pages open in an editorial dark register: a deep indigo navy {colors.primary} (#1b1938) canvas overlaid with a soft violet-and-sky atmospheric backdrop and a half-bleed portrait subject (often a person looking off-frame, photographed at twilight). Headlines render in {typography.display-xxl} (Super Sans VF at 64px / weight 540) with negative tracking, set in white over the indigo. A single rounded-rectangle CTA button anchors each band — never two, never three.

The body of every page flips to white. {colors.canvas} (#ffffff) takes over below the hero, with body type in {colors.ink} (#292827 — a slightly warm dark grey, never pure black) and feature rows alternating between white and {colors.canvas-soft} (a barely-tinted off-white). Pricing tiers sit on this white surface; the featured tier inverts to the indigo navy, completing the brand's binary polarity.

Every page closes with a deep-teal CTA band ({colors.surface-teal-deep} — #0e3030). The teal is a single chromatic interlude: rich, almost-black green-blue, that breaks up what would otherwise be an indigo/white-only page. The teal band always contains the closing CTA in {typography.display-lg} paired with a single white-pill button.

Typography runs Super Sans VF — a proprietary variable display sans — at unusual mid-weights (460, 540, 600). The variable axes let the brand pick precise sub-default weights that read as warmer and more human than typical 400/500/700 SaaS scales. Display sizes use negative letter-spacing of -1.32px to -0.315px depending on size; line-heights are unusually tight (0.96 on 48px display).

Key Characteristics:

Three-canvas system: indigo navy ({colors.primary}) for hero, white ({colors.canvas}) for body, deep teal ({colors.surface-teal-deep}) for closing CTA.
Half-bleed portrait subject in the hero with violet-sky atmospheric backdrop — the brand uses a person looking off-frame as a recurring visual.
Single CTA per band; the marketing pages never crowd actions.
Super Sans VF at sub-default weights (460, 540, 600) — the brand's typographic warmth signature.
Tight line-heights (0.96) on display sizes — vertical compression as editorial density.
Off-warm-grey body ink (#292827) — never pure black; the brand's quiet warmth.
Pill-shaped on-hero CTA in pale violet ({colors.surface-violet-soft}); rounded-rectangle CTAs everywhere else.

Do's and don'ts

Do

Pair every hero with the violet-sky atmospheric backdrop and a half-bleed portrait subject when possible.
Render display tiers at sub-default weights (460 / 540) — the warmth is the typographic signature.
Use rounded-rectangle CTAs at 8px radius everywhere except the hero (where pill-shaped is the rule).
Close every marketing page with a deep-teal CTA band.
Use warm dark grey {colors.ink} for body text — never pure black.
Apply tight 0.96 line-height on display sizes; the editorial compression is the brand.

Don't

Don't use pill-shaped buttons in the body of the page; the pill is hero-only.
Don't bump display weight above 540 unless using body-strong (700) for emphasized inline body.
Don't render body text in pure black — the warm grey #292827 is part of the brand.
Don't omit the closing teal band — every marketing page closes with it.
Don't introduce additional accent colors beyond indigo, violet-soft, teal, and the off-warm-greys.

Font Family

The display and UI tier is Super Sans VF — a proprietary variable sans (variable axes for weight, with the brand using sub-default 460 / 540 / 600 weights). Fallback chain is the system font stack.

For substitution use Inter Variable (open-source) at weight 460 / 540 / 600 — Inter's variable axes match Super Sans VF's behavior closely. Avoid fixed-weight Inter at 400 / 500 / 600 — the brand specifically picks the in-between weights.

Hierarchy

Token	Size	Weight	Line Height	Letter Spacing	Use
`{typography.display-xxl}`	64px	540	0.96	0	Hero headline
`{typography.display-xl}`	48px	460	0.96	-1.32px	Section opener on light surfaces
`{typography.display-lg}`	28px	540	1.14	-0.63px	Sub-section / feature title
`{typography.display-md}`	22px	460	1.1	-0.315px	Card title
`{typography.heading-lg}`	20px	460	1.2	-0.4px	Compact card title
`{typography.body-lg}`	18px	540	1.5	-0.135px	Marketing body lead
`{typography.body-md}`	16px	460	1.5	0	Default UI body
`{typography.body-strong}`	18.72px	700	1.5	0	Emphasized body
`{typography.button-md}`	16px	700	1.0	0	Rounded-rectangle button label
`{typography.button-cap}`	14px	600	1.0	0	Compact button label
`{typography.caption}`	14px	460	1.4	0	Helper, footnote
`{typography.micro}`	12px	540	1.4	0	Pill label, fine print

Principles

Sub-default weights. The brand picks 460 / 540 / 600 instead of 400 / 500 / 700 — a quiet warmth in the typography that distinguishes it from default SaaS systems.
Tight display leading. 0.96 on 48–64px display — the type stacks unusually compact.
Negative tracking on display sizes. -1.32px at 48px scaling proportionally — tightens the variable letterforms into editorial density.

Note on Font Substitutes

Inter Variable (open-source via Google Fonts) is the recommended substitute. Set font-variation-settings: "wght" 540 for display, 460 for body — Inter's variable axes match. Avoid fixed-weight Inter; the in-between weights are the brand's signature.

Components and layoutRead the full spec

Buttons

button-primary-dark — the dominant rounded-rectangle CTA on white surfaces.

Background {colors.primary}, text {colors.on-primary}, type {typography.button-md}, padding {spacing.md} {spacing.xl} (12px 20px), rounded {rounded.md} 8px.
Pressed state button-primary-dark-pressed shifts to {colors.primary-deep}.

button-on-dark-pill — the hero CTA in pale violet pill shape.

Background {colors.surface-violet-soft}, text {colors.primary}, same typography, padding 12px 20px, rounded {rounded.full}. The pill shape only appears on the hero — body CTAs use the rounded rectangle.

button-secondary-outline — outline alternative on white.

Background {colors.canvas}, text {colors.ink}, 1px solid {colors.hairline-dark} border, same shape as button-primary-dark.

button-on-teal — CTA inside the closing teal band.

Background {colors.canvas}, text {colors.surface-teal-deep}, rounded-rectangle, same typography.

Cards & Containers

card-feature-light — feature card on white.

Background {colors.canvas}, padding {spacing.xxl}, rounded {rounded.lg}, 1px {colors.hairline} border.

card-pricing — standard pricing tier card.

Background {colors.canvas}, padding {spacing.xxl}, rounded {rounded.lg}, 1px {colors.hairline} border.

card-pricing-featured — inverted indigo featured tier.

Background {colors.primary}, text {colors.on-primary}, otherwise identical to card-pricing.

card-teal-band — the closing CTA band on every page.

Background {colors.surface-teal-deep}, text {colors.on-primary}, padding {spacing.huge} 64px, rounded {rounded.lg} 12px (often radius-less in practice when full-bleed). Holds a single closing headline in {typography.display-lg} and a button-on-teal.

card-feature-row — alternating feature-row card on the body.

Background {colors.canvas-soft}, text {colors.ink}, padding {spacing.xl} 24px, rounded {rounded.md} 8px. Used in pairs/triplets to explain features below the hero.

Inputs & Forms

text-input — standard form input.

Background {colors.canvas}, text {colors.ink}, type {typography.body-md}, padding {spacing.sm}+ {spacing.md} (10px 12px), rounded {rounded.sm} 6px, 1px {colors.hairline} border.

Navigation

nav-bar-dark — top nav over the indigo hero.

Background {colors.primary}, text {colors.on-primary}, padding {spacing.lg} {spacing.xl}. Logo on the left, nav center, "Get Started" button-on-dark-pill on the right.

nav-bar-light — top nav on body / pricing pages.

Background {colors.canvas}, text {colors.ink}, otherwise same structure with button-primary-dark on the right.

Pills, Tags, and Chips

pill-tab-light — feature-row tab selector.

Background {colors.canvas}, text {colors.ink}, type {typography.button-cap}, padding {spacing.sm} {spacing.lg}, rounded {rounded.full}. Used in the feature category picker (Mail / Channels / Code / AI / Calendar etc.) below the hero.

Signature Components

Half-Bleed Portrait Hero — a person photographed at twilight, occupying the right half of the indigo hero with violet-sky atmospheric backdrop behind. Type and CTA sit on the left side. The portrait is the brand's recurring visual signature.

Closing Teal Band — every page closes with a card-teal-band containing a {typography.display-lg} closing headline and a single button-on-teal. The teal is the page's resolving chord.

link-on-light — inline links on body.

Text {colors.ink} rendered in {typography.body-md} with persistent underline.

footer-light — site-wide footer.

Background {colors.canvas}, text {colors.ink-mute}, type {typography.caption}, padding {spacing.huge} {spacing.xl} (64px 24px). Holds 4 columns of link groups, social icons, and a small legal/copyright row.

Spacing System

Base unit: 8px (with 2 / 4 / 12 sub-tokens for fine work).
Tokens: {spacing.xxs} 2px · {spacing.xs} 4px · {spacing.sm} 8px · {spacing.md} 12px · {spacing.lg} 16px · {spacing.xl} 24px · {spacing.xxl} 32px · {spacing.huge} 64px.
Section padding: 64–96px on most sections; closing teal band uses 96–128px for editorial weight.
Card internal padding: 32px on pricing cards; 24px on alternating feature rows.

Responsive behaviourRead the full spec

Breakpoints

Name	Width	Key Changes
Wide	≥ 1440px	Half-bleed portrait at full scale; teal band 128px tall
Desktop	1024–1440px	Default content max-width; pricing 3-up
Tablet	768–1023px	Pricing 2-up; portrait crops tighter
Mobile	< 768px	Pricing 1-up; hamburger nav; display drops 64 → 36px

Touch Targets

Buttons hit ≥ 44×44px on mobile via 12px vertical padding × 16px line-height. WCAG AAA.
Form fields stay at the 44px minimum height.

Collapsing Strategy

Display tiers stair-step 64 → 48 → 36 → 28 → 22px.
Half-bleed portrait crops to head-and-shoulders on mobile; atmospheric backdrop simplifies.
Pricing tiers stair-step 3-up → 2-up → 1-up.
Top nav collapses to hamburger below 768px.
Closing teal band reduces vertical padding from 128 → 64px on mobile.

Image Behavior

Hero portrait uses srcset with desktop / mobile crops — desktop favors the full half-bleed composition; mobile crops to head-and-shoulders.
