Revolut's marketing surfaces pair a stark black canvas with the brand's

cobalt-violet (`#494fdf`) and a wide accent palette of deep, fully-saturated

product colours — teal, light-blue, deep pink, light-green, warning orange.

The system reads as fintech-meets-product-brochure: oversized 80px–136px

Aeonik Pro display headlines, generous whitespace, photography-led hero

bands, and full-width product mockups (cards, phones, terminals) shown as

hero objects inside near-black sections. Most surfaces are either black or

off-white; pill-shaped buttons and rounded-12/20px content cards carry the

consumer-financial-app feel without crossing into playful territory.

Overview

Section 01

Revolut's marketing canvas operates in a high-contrast two-mode system: a

**near-black storytelling canvas** (`{colors.canvas-dark}` — `#000000`)

that hosts hero bands, product mockups, and the planning section, alternating

with **white catalogue bands** (`{colors.canvas-light}` — `#ffffff`) that

host comparison tables, FAQ rows, and download tiles. The two modes switch

in full-bleed bands rather than soft transitions; sections slam against each

other to create the magazine-spread rhythm the brand is known for.

The display typography is **Aeonik Pro at weight 500**, used at sizes from

20px to 136px. The flagship hero ("Banking & Beyond", "Join the 70+ million

using Revolut") sits at 80–136px with `lineHeight: 1.0` and tight negative

letter-spacing. Body type is **Inter** at weight 400 — open-source,

no-nonsense, paired with positive tracking (`0.24px`) on UI labels for

slightly more mechanical precision.

The brand accent is `{colors.primary}` (`#494fdf`) — a saturated cobalt

violet — but it appears scarcely on marketing surfaces. The actual primary

CTA on the hero is the **white pill on black** ("Choose your subscription"),

and the cobalt violet is reserved for featured plan cards, secondary CTAs in

white sections, and the brand glyph itself. A wide secondary palette of deep

teal, light-blue, deep-pink, light-green, warning orange, and yellow appears

inside product mockups and feature illustrations — never as button surfaces.

**Key Characteristics:**

Two-mode canvas system — `{colors.canvas-dark}` (true black) for storytelling, `{colors.canvas-light}` (white) for browsing — switched in full-bleed bands.

Display typography is **Aeonik Pro 500** at sizes 20–136px with tight `lineHeight: 1.0` and large negative letter-spacing on display sizes.

The actual primary CTA is `{component.button-primary}` — a **white pill with black text**, sitting on the dark canvas as the brightest pixel. Cobalt-violet `{colors.primary}` is reserved for featured plan cards and secondary CTAs.

Eight saturated accent colours live inside product mockups and illustrations only, never as button surfaces — teal, light-blue, deep-pink, light-green, warning orange, yellow, brown, danger red.

All buttons are pill-shaped (`{rounded.full}`); content cards use `{rounded.lg}` (20px); inputs and small chips use `{rounded.md}` (12px).

Photography is product-led — phone mockups, card mockups, terminal mockups — shown full-bleed inside dark sections with no caption overlay.

Colors

Section 02

Brand & Accent

Section 03

Cobalt Violet (`{colors.primary}` — `#494fdf`): the brand accent. Reserved for featured plan cards (`{component.plan-card-featured}`), the brand wordmark icon, and secondary CTAs in white-canvas regions.

Cobalt Bright (`{colors.primary-bright}` — `#4f55f1`): a one-step-up bright variant used in inline link colour and accent-photo headers.

Cobalt Deep (`{colors.primary-deep}` — `#3a40c4`): the active/pressed state of cobalt elements.

On-Primary (`{colors.on-primary}` — `#ffffff`): label colour on top of `{colors.primary}` surfaces.

Surface

Section 04

Canvas Light (`{colors.canvas-light}` — `#ffffff`): the white catalogue mode for FAQ, download tiles, comparison tables.

Canvas Dark (`{colors.canvas-dark}` — `#000000`): the storytelling canvas — true black, never near-black.

Surface Soft (`{colors.surface-soft}` — `#f4f4f4`): a subtle off-white used on download tiles, soft buttons, and inset card groups inside white bands.

Surface Card (`{colors.surface-card}` — `#ffffff`): pure white card surface, used for feature cards in white-canvas regions.

Surface Deep (`{colors.surface-deep}` — `#0a0a0a`): a one-step-up dark surface for inset cards inside black-canvas regions.

Surface Elevated (`{colors.surface-elevated}` — `#16181a`): the planning-section card background — slightly luminous, lifts plan cards off the black canvas.

Hairline Light (`{colors.hairline-light}` — `#e2e2e7`): 1px dividers inside white bands.

Hairline Dark (`{colors.hairline-dark}` — `rgba(255,255,255,0.12)`): the corresponding low-contrast divider in dark regions.

Hairline Strong (`{colors.hairline-strong}` — `#191c1f`): structural full-strength dividers and the outline of light cards.

Text

Section 05

Ink (`{colors.ink}` — `#191c1f`): primary text colour. Notably warmer than pure black, paired with the white canvas for body legibility.

Body (`{colors.body}` — `#1f2226`): long-form body where `{colors.ink}` would feel slightly too sharp.

Charcoal (`{colors.charcoal}` — `#3a3d40`): captions, secondary nav.

Mute (`{colors.mute}` — `#505a63`): supporting text.

Ash (`{colors.ash}` — `#5c5e60`): tertiary text, footer copy.

Stone (`{colors.stone}` — `#8d969e`): metadata, subtle captions.

Faint (`{colors.faint}` — `#c9c9cd`): disabled foreground, hairline replacements.

On-Dark (`{colors.on-dark}` — `#ffffff`): primary text on `{colors.canvas-dark}`.

On-Dark Mute (`{colors.on-dark-mute}` — `rgba(255,255,255,0.72)`): secondary text in dark regions.

Semantic

Section 06

Accent Teal (`{colors.accent-teal}` — `#00a87e`): used in product mockup illustrations.

Accent Light Blue (`{colors.accent-light-blue}` — `#007bc2`): inline link colour in dark photo headers.

Accent Blue Link (`{colors.accent-blue-link}` — `#376cd5`): default inline link colour on white surfaces.

Accent Light Green (`{colors.accent-light-green}` — `#428619`): success / positive product callouts.

Accent Green Text (`{colors.accent-green-text}` — `#006400`): inline success text.

Accent Yellow (`{colors.accent-yellow}` — `#b09000`): caution / pending state in product mockups.

Accent Warning (`{colors.accent-warning}` — `#ec7e00`): full-saturation orange used in warning illustrations.

Accent Pink (`{colors.accent-pink}` — `#e61e49`): deep pink — used inside product photography and category iconography.

Accent Danger (`{colors.accent-danger}` — `#e23b4a`): destructive / error state.

Accent Deep Red (`{colors.accent-deep-red}` — `#8b0000`): inline error text.

Accent Brown (`{colors.accent-brown}` — `#936d62`): a single warm-neutral used in metals tier card chrome.

Link (`{colors.link}` — `#376cd5`): default inline link colour. Same as `{colors.accent-blue-link}`.

Typography

Section 07

Font Family

Section 08

Revolut ships a two-family stack:

Aeonik Pro — proprietary humanist sans-serif used for all display sizes (20px+) at weight 500. Carries the brand's editorial confidence; tightens dramatically with negative letter-spacing at large sizes.

Inter — open-source workhorse for body, button labels, captions, and metadata. Always at weight 400 or 600, with positive tracking (`0.16–0.24px`) on UI labels.

When Aeonik Pro cannot be licensed, **Inter Display**, **General Sans**, or **Söhne** are credible substitutes — all share the warm geometric character. Apply -1% letter-spacing on display sizes to match the original tightness.

Hierarchy

Section 09

|---|---|---|---|---|---|

| `{typography.display-xxl}` | 136px | 500 | 1.0 | -2.72px | The flagship hero ("Banking & Beyond"). One per page. |

| `{typography.display-xl}` | 80px | 500 | 1.0 | -0.8px | Section openers ("Join the 70+ million using Revolut"). |

| `{typography.display-lg}` | 48px | 500 | 1.21 | -0.48px | Sub-section titles. |

| `{typography.display-md}` | 40px | 500 | 1.2 | -0.4px | Feature card titles. |

| `{typography.heading-lg}` | 32px | 500 | 1.19 | -0.32px | Plan card titles. |

| `{typography.heading-md}` | 24px | 500 | 1.33 | 0 | Section sub-titles. |

| `{typography.heading-sm}` | 20px | 500 | 1.4 | 0 | List headers, prominent labels. |

| `{typography.body-lg}` | 18px | 400 | 1.56 | -0.09px | Marketing prose. |

| `{typography.body-md}` | 16px | 400 | 1.5 | 0.24px | Default body. |

| `{typography.body-md-bold}` | 16px | 600 | 1.5 | 0.16px | Emphatic body. |

| `{typography.body-sm}` | 14px | 400 | 1.43 | 0 | Captions, metadata. |

| `{typography.button-lg}` | 20px | 500 | 1.4 | 0 | Hero CTAs (Aeonik Pro). |

| `{typography.button-md}` | 16px | 600 | 1.5 | 0.24px | Default button label. |

| `{typography.button-sm}` | 14px | 600 | 1.43 | 0 | Pill chips, sub-nav. |

| `{typography.caption}` | 13px | 400 | 1.4 | 0 | Footer disclosure, regulatory text. |

| `{typography.link-emph}` | 16px | 700 | 1.5 | 0.24px | Emphatic inline link in dark mode. |

Principles

Section 010

Display sizes always run at weight 500 with `lineHeight: 1.0` (or 1.19–1.21 below 48px). The negative letter-spacing scales with size — bigger types tighten more.

Body Inter sits at weight 400 with positive tracking (`0.24px`) — the small spacing nudge makes UI labels feel slightly mechanical, fitting fintech precision.

Hero CTAs use the Aeonik Pro `{typography.button-lg}` variant; everything below the hero uses the Inter `{typography.button-md}`.

Inline links inside dark photo regions step up to weight 700 (`{typography.link-emph}`) so they hold contrast against the canvas without using the cobalt accent.

Note on Font Substitutes

Section 011

When Aeonik Pro is unavailable, clamp display `lineHeight` to 1.0 explicitly and apply -1% letter-spacing on display sizes. Inter Display, General Sans, or Söhne will read closest to the original. Inter is open-source and should be used directly.

Layout

Section 012

Spacing System

Section 013

Base unit: 4px, with the working scale on multiples of 4 / 8 / 16.

Tokens: `{spacing.xxs}` 4px · `{spacing.xs}` 6px · `{spacing.sm}` 8px · `{spacing.md}` 14px · `{spacing.lg}` 16px · `{spacing.xl}` 24px · `{spacing.xxl}` 32px · `{spacing.xxxl}` 48px · `{spacing.block}` 80px · `{spacing.section}` 88px · `{spacing.band}` 120px.

Section padding: `{spacing.section}` (88px) vertical between bands; `{spacing.band}` (120px) on the hero band and the closing planning section.

Card internal padding: `{spacing.xxl}` (32px) on `{component.feature-card-light}`, `{component.plan-card}`, `{component.feature-card-dark}`.

Grid & Container

Section 014

Max content width ≈ 1200px on body sections; hero bands run full-bleed.

Plan grid: 4-up plan cards on the home page, stacking 2-up at tablet and 1-up at small mobile.

Feature grid: 3-up at desktop, 2-up at tablet, 1-up at mobile.

Product mockup bands: a single full-width hero photo of a phone or card mockup, no surrounding chrome — the asset itself is the section.

Whitespace Philosophy

Section 015

Whitespace is generous and editorial — sections breathe at 88–120px so display headlines have room to register at 80–136px without feeling cramped.

Inside cards, padding stays at 32px so feature copy and plan tiers have a consistent rhythm.

Hairline `{colors.hairline-light}` dividers replace shadow on white surfaces; `{colors.hairline-dark}` carries the corresponding role in dark regions.

Elevation & Depth

Section 016

| Level | Treatment | Use |

|---|---|---|

| 0 — flat | No shadow, no border | Default canvas bands (light or dark), full-bleed hero. |

| 1 — surface card | `{colors.surface-card}` (white) on `{colors.surface-soft}` band | Feature cards inside light bands. |

| 2 — surface elevated dark | `{colors.surface-elevated}` (`#16181a`) on `{colors.canvas-dark}` | Plan cards inside the planning section. |

| 3 — featured surface | `{colors.primary}` on `{colors.canvas-dark}` | Featured plan card (cobalt violet inversion). |

| 4 — product mockup | Full-bleed photo asset | Hero phone / card / terminal mockup bands. |

The system has **no traditional drop-shadow language**. Surfaces register depth via colour-blocking (light → dark band switches) and surface-luminance shifts (`{colors.canvas-dark}` → `{colors.surface-elevated}`). Photography mockups carry their own depth from the asset itself.

Decorative Depth

Section 017

Product mockup hero bands — the home page features a phone mockup full-bleed against `{colors.canvas-dark}`, with the device's own glow providing the only atmospheric depth. No additional gradients, no shadows.

Featured plan card — the cobalt-violet `{component.plan-card-featured}` sits inside the otherwise dark planning grid as a single saturated colour block, marking the recommended tier visually.

Card metals tier — the brand uses `{colors.accent-brown}` and a deep gradient on metals card mockups to signal premium without resorting to gold-on-black metallic effects.

Shapes

Section 018

Border Radius Scale

Section 019

| Token | Value | Use |

|---|---|---|

| `{rounded.none}` | 0px | Hero bands, full-bleed sections, footer. |

| `{rounded.sm}` | 8px | Inline tags, small chips. |

| `{rounded.md}` | 12px | Form inputs, download tiles. |

| `{rounded.lg}` | 20px | Feature cards, plan cards. |

| `{rounded.xl}` | 28px | Product mockup containers. |

| `{rounded.full}` | 9999px | Buttons, pills, badges, tabs. |

Navigation

Section 025

**`nav-bar`** — top nav (desktop)

Background `{colors.canvas-dark}`, text `{colors.on-dark}`, type `{typography.button-md}`, height 64px.

Left: wordmark logo. Centre: top-level nav ("Personal", "Business", "Company"). Right: language switcher + "Log in" + `{component.button-primary}`.

**`nav-bar`** (mobile)

Same height 64px, collapses centre nav into a hamburger icon. Logo stays left, sign-in CTA stays right.

**`sub-nav-pill`** — sub-nav chip

Pill chips set in a horizontal row inside dark sections (e.g. "Personal", "Business", "Premium"), `{component.sub-nav-pill}` styling.

Signature Components

Section 026

**`badge-tag`** — neutral tag

Background `{colors.surface-soft}`, text `{colors.ink}`, type `{typography.caption}`, `rounded: {rounded.full}`, padding `4px 12px`.

Inline tags inside feature cards.

**`badge-feature`** — feature highlight badge

Background `{colors.primary}`, text `{colors.on-primary}`, type `{typography.caption}`, `rounded: {rounded.full}`, padding `4px 12px`.

"New", "Most popular" badges anchored on plan cards.

**`footer`** — global footer

Background `{colors.canvas-dark}`, text `{colors.on-dark-mute}`, type `{typography.body-sm}`, `rounded: {rounded.none}`, padding `80px 24px`.

Multi-column quick-links grid above a copyright + regulatory disclosure block separated by `{colors.divider-soft}`.

Do's and Don'ts

Section 027

Do

Section 028

Switch full bands between `{colors.canvas-dark}` (storytelling) and `{colors.canvas-light}` (catalogue). The two-mode rhythm is core.

Use `{component.button-primary}` (white pill on dark) as the primary CTA on every dark hero band. It's the brand's loudest action.

Reserve `{colors.primary}` for the featured plan card and the brand wordmark — the cobalt should feel like a deliberate stamp, not a colour theme.

Set hero headlines in **Aeonik Pro 500** at 80–136px with `lineHeight: 1.0` and large negative letter-spacing.

Use **Inter** for body, button labels, captions — never substitute Aeonik Pro for body type.

Apply `{rounded.full}` to every button and pill; `{rounded.lg}` (20px) to feature and plan cards; `{rounded.md}` (12px) to inputs.

Show product mockups full-bleed inside dark sections — the asset IS the section.

Use the wide accent palette (`{colors.accent-teal}`, `{colors.accent-pink}`, `{colors.accent-light-green}`, etc.) inside product illustrations and iconography only.

Don't

Section 029

Don't use accent colours (`{colors.accent-teal}`, `{colors.accent-pink}`, etc.) as button surfaces. They live inside illustrations only.

Don't use a near-black canvas. The brand is `#000000`, not `#0a0a0a`.

Don't pair white text with cobalt violet inside body content — `{colors.primary}` is for the featured plan card surface, not large prose.

Don't add drop shadows on cards. Elevation is canvas + surface-luminance shifts.

Don't introduce a secondary brand colour. Cobalt violet is the only brand stamp.

Don't loosen Aeonik Pro `lineHeight` past 1.0 on display sizes. Tight stacking is structural.

Don't bump body Inter to weight 500. Use 400 (default) or 600 (emphatic) — never the in-between.

Don't pair `{colors.canvas-dark}` with another dark surface beyond `{colors.surface-elevated}`. The surface ladder has only two dark steps.

Responsive Behavior

Section 030

Breakpoints

Section 031

| Name | Width | Key Changes |

|---|---|---|

| Desktop XL | ≥ 1440px | 4-up plan grid, full-bleed product mockup bands, max content 1200. |

| Desktop | 1280–1439px | Container shrinks; xl side padding. |

| Tablet Large | 1024–1279px | Plan grid 4-up; feature grid 3-up. |

| Tablet | 768–1023px | Plan grid 2-up; feature grid 2-up. |

| Mobile Large | 426–767px | Plan grid 1-up; feature grid 1-up; nav collapses to hamburger; hero `display-xxl` clamps to 64px. |

| Mobile | ≤ 425px | All grids 1-up; hero clamps to 48px; section padding `{spacing.section}` collapses to 64px. |

Touch Targets

Section 032

All buttons ship at minimum 48px tall — comfortably exceeds WCAG AAA (44px). Default `{component.button-primary}` is 48px.

`{component.text-input}` is 56px tall — fintech-grade accessibility.

`{component.button-pill-sm}` (36px) is bumped to 44px on mobile via padding adjustment.

Collapsing Strategy

Section 033

Top-level nav collapses to hamburger at < 1024px; the wordmark and `{component.button-primary}` stay anchored.

Hero `{typography.display-xxl}` clamps: 136px → 80px → 64px → 48px across the breakpoint ladder.

Plan grid steps from 4-up to 2-up at < 1024px to 1-up at < 768px.

Product mockup bands maintain full-bleed at every breakpoint; the asset crops inward rather than letterboxing.

Sub-nav pills convert from a wrap row to a horizontal scroll-rail at < 768px.

Image Behavior

Section 034

Phone and card mockups are served at 1.5× and 2× DPR; below 768px the system swaps to a smaller hero crop.

Product photography retains its own atmospheric lighting at every breakpoint — no responsive variant assets.

Iteration Guide

Section 035

1. Focus on ONE component at a time. Most surfaces share the `{colors.canvas-dark}` / `{colors.canvas-light}` pair with `{rounded.full}` for buttons and `{rounded.lg}` for cards.

2. Reference component names and tokens directly (`{colors.primary}`, `{component.plan-card-featured}`, `{rounded.lg}`) — do not paraphrase.

3. Run `npx @google/design.md lint DESIGN.md` after edits; orphaned-tokens warnings will catch unused entries.

4. Add new variants as separate entries (`-pressed`, `-featured`, `-disabled`) — do not bury them in prose.

5. Default body type to `{typography.body-md}` (Inter 400 with positive tracking); reach for `{typography.body-md-bold}` only on emphasis.

6. Keep `{colors.primary}` scarce — if more than one cobalt-violet element appears per viewport, ask whether one should drop to `{component.plan-card}` (`{colors.surface-elevated}`) instead.

Known Gaps

Section 036

Pressed/active visual states are documented for `button-primary-pressed` only; other components rely on focus-ring (browser default) for interactive feedback.

Logged-in app surfaces (transactions, transfers, account settings) are out of scope — only the public marketing canvas is documented.

The wide accent palette (`{colors.accent-teal}` through `{colors.accent-brown}`) is captured from the extracted token set, but exact usage inside product illustrations varies per market and product line; document per-illustration rather than as system buttons.

Mobile-app screenshot art direction (phone bezels, status bars) is product-photography territory and not standardised as design tokens.
