version: alpha name: Mistral AI description: Mistral AI brands itself with a singular signature — atmospheric sunset gradients (mustard, orange, deep red) layered over photography of mountains, plus a horizontal "sunset stripe" bar that closes every page. The system pairs warm cream-yellow surfaces ({colors.cream}) with a saturated orange primary CTA ({colors.primary}) and uses an elegant near-serif voice for hero displays. Coverage spans homepage (Frontier AI hero), Le Studio product page, Coding solutions, news article surfaces, contact form, and services tier page — all anchored by the signature gradient closing band.

Overview

Mistral AI carries itself with a singular, almost cinematographic visual signature — the homepage opens with "Frontier AI. In your hands." rendered in elegant near-serif display type over a photographic mountain landscape bathed in mustard-orange sunset light. Below the hero, every page closes with the same recognizable element: a horizontal "sunset stripe" gradient band running red→orange→yellow→cream that wraps the foot of the page just above the footer. This stripe is THE brand recognizer — it appears on the homepage, products/studio, solutions/coding, news articles, contact form, and services tier page without exception.

The system pairs PP Editorial Old (a near-serif elegant display face) for hero displays with Inter for everything else (body, headings, UI). Cream-yellow surfaces ({colors.cream}, {colors.surface-cream-soft}) anchor form panels and feature cards; saturated orange ({colors.primary}) carries primary CTAs; the deep mountain photography on the homepage and the dark code mockups inside Le Studio create photographic depth. Cards are rectangular with {rounded.lg} (12px) corners — distinctly less playful than Miro's or Mintlify's pill-buttons-everywhere approach. Buttons are also {rounded.md} (8px), not pills — Mistral's geometry is more sober and editorial than its peers.

Key Characteristics:

Atmospheric mountain-sunset hero photography (orange-red-yellow gradient sky)
Horizontal "sunset stripe" band ({colors.primary} → {colors.sunshine-700} → {colors.yellow-saturated} → {colors.cream}) at every page bottom
Cream-yellow surfaces ({colors.cream}, {colors.cream-soft}) for form panels and feature cards
PP Editorial Old (or similar near-serif) for hero displays; Inter for everything else
{rounded.md} (8px) buttons and {rounded.lg} (12px) cards — less playful, more editorial geometry
Saturated orange primary CTA ({colors.primary}) carries every action call

Principles

Editorial / sans pairing — PP Editorial Old (near-serif, classical) anchors hero displays; Inter (geometric sans) carries everything else. The contrast IS the brand voice.
Generous body leading (1.55 on body-md) for editorial readability across long-form pages
Tight hero leading (1.05 on 84px display) creates magazine-grade typographic display
Negative letter-spacing progresses with size — display sizes use -1.5px to -0.5px; smaller heads relax to 0
Stat-display token (56px Editorial) for marketing stat callouts ("75% / 80% / 100%")

Layout

Spacing System

Base unit: 4px (8px primary increment)
Tokens: {spacing.xxs} (4px) · {spacing.xs} (8px) · {spacing.sm} (12px) · {spacing.md} (16px) · {spacing.lg} (20px) · {spacing.xl} (24px) · {spacing.xxl} (32px) · {spacing.xxxl} (40px) · {spacing.section-sm} (48px) · {spacing.section} (64px) · {spacing.section-lg} (96px) · {spacing.hero} (120px)
Section rhythm: Marketing pages use {spacing.section-lg} (96px); content pages tighten to {spacing.section} (64px)
Card internal padding: {spacing.xl} (24px) for compact cards; {spacing.xxl} (32px) for feature panels and form panels

Grid & Container

Marketing pages use 1280px max-width with 32px gutters
Hero band uses 2-column split (text left, sunset photography right) on desktop
Le Studio product page uses 3-up feature grid below the hero
Contact page uses 1-column layout with cream form panel centered (~520px max-width)
Services page uses 4-tier card layout with cream feature panel separator strip

Whitespace Philosophy

Marketing surfaces give content generous breathing room — {spacing.hero} (120px) hero padding lets the mountain-sunset photography fill the frame. Form pages tighten dramatically: contact form panel uses {spacing.xxl} (32px) internal padding, fields stack on {spacing.md} (16px) gap.

Elevation & Depth

The system runs predominantly flat with strategic atmospheric depth from photography.

Level	Treatment	Use
0 (flat)	No shadow; `{colors.hairline-soft}` border	Default cards, table rows, form inputs
1 (subtle)	`rgba(0, 0, 0, 0.04) 0px 1px 2px 0px`	Hover-elevated tiles
2 (card)	`rgba(0, 0, 0, 0.04) 0px 4px 12px 0px`	Standard feature cards
3 (mockup)	`rgba(0, 0, 0, 0.08) 0px 12px 24px -4px`	IDE mockup, code editor frames
4 (modal)	`rgba(0, 0, 0, 0.12) 0px 16px 48px -8px`	Modals, dropdowns

Decorative Depth

The atmospheric depth on Mistral's hero comes from the photographic mountain-sunset imagery — natural light gradient does the work
The "sunset stripe" closing band carries depth via its multi-stop gradient (red → orange → yellow → cream)
IDE / code mockups use dark-canvas backgrounds with subtle drop shadow

Shapes

Border Radius Scale

Token	Value	Use
`{rounded.xs}`	4px	Small chips, micro-controls
`{rounded.sm}`	6px	Discount badges, compact UI
`{rounded.md}`	8px	Buttons, inputs, search-pill, code blocks
`{rounded.lg}`	12px	Cards, modals, panels (the dominant card radius)
`{rounded.xl}`	16px	Larger feature panels
`{rounded.xxl}`	20px	Featured emphasis cards
`{rounded.full}`	9999px	Status badges, pill tabs (used sparingly — most buttons are NOT pills)

The radius scale is sober and editorial — Mistral does NOT use pill buttons. {rounded.md} (8px) for buttons, {rounded.lg} (12px) for cards, {rounded.full} reserved for badges and the rare pill tab.

Photography Geometry

Hero photography is full-bleed atmospheric mountain-sunset imagery with no internal framing
IDE/code mockups render with {rounded.lg} (12px) corners on dark canvas
Customer logos wall presents wordmarks inline at consistent 60–80px height
Product imagery (Le Studio mockup, agent UI mockups) sits in {rounded.lg} panels with subtle border

Background gradient linear-gradient(135deg, {colors.sunshine-700} 0%, {colors.sunshine-900} 60%, {colors.primary} 100%) overlaid on photographic mountain landscape.
Layout: hero headline left in {typography.hero-display} ({colors.ink}), subtitle in {typography.subtitle} ({colors.ink-tint}), button row (button-dark + button-secondary), atmospheric mountain photography right.

sunset-stripe-band — Horizontal closing band at the foot of every page.

Multi-stop gradient: {colors.primary} → {colors.sunshine-700} → {colors.sunshine-500} → {colors.yellow-saturated} → {colors.cream}.
Padding {spacing.lg} 0. Spans full width, sits above the footer. THIS IS THE BRAND'S MOST RECOGNIZABLE SIGNATURE ELEMENT.

cta-banner-cream — Page-bottom CTA band on cream surface.

Background {colors.cream}, text {colors.ink}, rounded {rounded.lg}, padding {spacing.section}. "The next chapter of AI is yours." headline in {typography.heading-1} (PP Editorial Old), button row below.

footer-region — Cream-tinted multi-column footer.

Background {colors.footer-cream}, padding {spacing.section} {spacing.xxl}.
5-column link grid (Why Mistral / Explore / Build / Legal + brand mark column).
Bottom: language picker + social icons.

footer-link — Individual footer link.

Background transparent, text {colors.primary}, typography {typography.body-sm}, padding {spacing.xxs} 0.

Do's and Don'ts

Do

Reserve {colors.primary} (saturated orange) for primary CTAs and active states only
Use the sunset stripe band at the foot of every page — it's the brand's most recognizable signature
Pair PP Editorial Old (display) with Inter (UI) — never substitute either with a generic alternative
Apply {rounded.md} (8px) to buttons and {rounded.lg} (12px) to cards consistently
Use cream-yellow surfaces ({colors.cream}) for form panels, feature cards, and footer
Anchor heroes with photographic mountain-sunset imagery (or its visual equivalent — atmospheric gradient sky)
Use stat-display token (PP Editorial 56px) for stat callouts to maintain editorial character

Don't

Don't use pill-shaped buttons ({rounded.full}) — Mistral's geometry is sober and editorial, not playful
Don't introduce additional accent colors beyond the orange/yellow/cream sunset palette
Don't reduce hero leading below 1.05 — the editorial display needs that magazine-grade tightness
Don't replace PP Editorial Old hero displays with Inter — the editorial / sans contrast IS the brand
Don't apply heavy shadows on flat documentation cards; reserve elevation for IDE mockups
Don't drop the sunset stripe band from any page bottom — it's the brand's continuity element

Responsive Behavior

Breakpoints

Name	Width	Key Changes
Mobile (small)	< 480px	Single column. Hero scales to 40px (PP Editorial). Pill nav collapses to hamburger. Pricing tiers stack 1-up.
Mobile (large)	480 – 767px	Feature tiles 2-up. Hero scales to 52px.
Tablet	768 – 1023px	2-column feature grids. Pill-tab nav returns. Hero 64px.
Desktop	1024 – 1279px	Multi-column layouts. Hero 76px. Stat row at full width.
Wide Desktop	≥ 1280px	Full 84px hero presentation.

Touch Targets

Buttons render at 40–44px effective height — at WCAG AAA floor with 10px 20px padding
Form inputs render at 44px height
Pill tabs render at ~32px tall — bumps to 44px on mobile

Collapsing Strategy

Promo banner stays full-width; truncates at < 480px
Top nav below 1024px collapses to hamburger
Hero band: 2-column hero (text + photography) collapses to stacked at < 1024px
Pricing tiers: 4-column desktop → 2-column tablet → 1-column mobile
Stat row: 3-column → stacked at < 768px
Hero typography: 84px → 64px → 52px → 40px
Footer: 5-column desktop → 3-column tablet → 1-column accordion mobile
Sunset stripe band stays full-width on all breakpoints

Image Behavior

Mountain-sunset photography uses 16:9 ratio with full-bleed scaling
IDE mockup images maintain aspect ratio across breakpoints
Customer logo wall presents wordmarks at consistent 60–80px height

Iteration Guide

Focus on ONE component at a time
Reference component names and tokens directly ({colors.primary}, {component-name}-pressed)
Run npx @google/design.md lint DESIGN.md after edits
Add new variants as separate components: entries
Default to {typography.body-md} for body and {typography.subtitle} for emphasis. Hero displays use {typography.hero-display} (PP Editorial Old).
Keep {colors.primary} confined to primary CTAs, active states, and the sunset stripe band
Cards use {rounded.lg} (12px), buttons use {rounded.md} (8px). Pills ({rounded.full}) reserved for badges only.
Always include the sunset-stripe-band component at the foot of every page mockup.

Known Gaps

Specific dark-mode token values not surfaced; the brand has not shipped a published dark-mode palette
Animation/transition timings not extracted; recommend 150–200ms ease for hover/focus state transitions
Form validation success state not explicitly captured beyond defaults
Sunset stripe band gradient stops are approximations — the actual values may vary slightly across pages but the visual rhythm is consistent
