version: alpha name: MongoDB description: MongoDB carries a strong dual-mode visual identity — dark deep-teal hero bands with bright MongoDB green ({colors.brand-green}) CTAs paired with stark white documentation surfaces. The signature green pill button is unmistakable across product, pricing, learning, and AI use-case surfaces. The system uses Euclid Circular A as its display face, anchors a 3-tier pricing comparison (Free / Flex / Dedicated), and presents extensive course catalogs in card grids with colored category tags. Coverage spans homepage, Atlas product page, Community Edition, MongoDB University, AI use cases, and pricing.

Overview

MongoDB carries a strong dual-mode visual identity — dark deep-teal hero bands with the unmistakable bright MongoDB green ({colors.brand-green}) CTA pill paired with stark white documentation and pricing surfaces. The homepage opens with "One data platform. Unlimited AI potential." headline over a deep navy hero, the green pill sitting at the visual center as the primary CTA. Lower on the page, embedded code mockup cards (terminal-aesthetic) sit on the dark hero band, breaking out into white feature cards below. The pricing page renders a 3-tier comparison (Free / Flex / Dedicated) with a featured tier highlighted in soft mint background and bright green border. The MongoDB University page presents a course catalog grid where each tile carries a colored category tag (orange, purple, green, teal) — these are MongoDB's category-encoding accent colors and are the only place outside the brand green where saturated color appears.

The system uses Euclid Circular A as its display face. The face is contemporary geometric — confident but not overly playful — and pairs naturally with both the developer-tool aesthetic of the database product and the educational positioning of the learning surfaces. Cards use {rounded.lg} (12px) corners; buttons use {rounded.full} pills universally. The brand-teal palette ({colors.brand-teal-deep}) anchors hero bands, footer, code mockups, and the dark CTA banners.

Key Characteristics:

Deep navy/teal hero bands ({colors.brand-teal-deep}) with bright MongoDB green ({colors.brand-green}) CTA pills
Stark white pricing/documentation surfaces with colored category tags for course tiles (purple, orange, green, teal)
Euclid Circular A across every UI surface
Pill-shaped buttons ({rounded.full}) and 12px-rounded cards
3-tier pricing comparison (Free / Flex / Dedicated) with featured-mint highlight tier
Code mockup cards with terminal-aesthetic dark canvas

Principles

Tight hero leading (1.10) on 72px display
Negative letter-spacing on display sizes (-1.5px to -0.5px)
600 weight reserved for buttons and small emphasis (FAQ headings, badges)
Generous body leading (1.55) for technical documentation readability

Layout

Spacing System

Base unit: 4px (8px primary increment)
Tokens: {spacing.xxs} (4px) through {spacing.hero} (120px)
Section rhythm: Marketing pages use {spacing.section-lg} (96px); pricing tightens to {spacing.section} (64px)

Grid & Container

1280px max-width with 32px gutters
Pricing: 3-tier card row, dense feature comparison table below
Learn catalog: 3-up course tile grid, 4-up certification grid
AI use cases: 2-column hero with atmospheric illustration

Whitespace Philosophy

Marketing surfaces give content generous breathing room — {spacing.hero} (120px) hero padding for deep teal bands. Pricing/learn surfaces tighten dramatically.

Elevation & Depth

Level	Treatment	Use
0 (flat)	No shadow; `{colors.hairline}` border	Default cards, table rows

2 (card)	`rgba(0, 30, 43, 0.08) 0px 4px 12px 0px`	Feature cards

Do's and Don'ts

Do

Use {colors.brand-green} (bright MongoDB green) for primary CTAs everywhere
Pair dark-teal hero bands with bright green CTA pills
Apply {rounded.full} to every button, every status badge
Apply {rounded.lg} (12px) to cards consistently
Use category accent colors (purple, orange, green, teal) ONLY for course tags
Maintain Euclid Circular A across every UI surface
Use code mockup cards with terminal-aesthetic content for product showcases

Don't

Don't use the bright green for body text or large surfaces
Don't introduce additional accent colors beyond the brand green and category-encoding palette
Don't soften corners on buttons; the pill is a brand signature
Don't replace deep teal hero bands with white hero bands
Don't apply heavy shadows on flat documentation cards; reserve elevation for code mockups
Don't use Source Code Pro for prose

Hero band: code mockup card moves below text on mobile
Pricing tiers: 3-column → 2-column tablet → 1-column mobile
Course catalog: 3-up → 2-up tablet → 1-up mobile
Hero typography: 72px → 56px → 48px → 36px
Footer: 6-column desktop → 3-column tablet → accordion mobile

Image Behavior

Iteration Guide

Focus on ONE component at a time
Reference component names and tokens directly
Run npx @google/design.md lint DESIGN.md after edits
Add new variants as separate components: entries
Default to {typography.body-md} for body
Keep {colors.brand-green} as the primary CTA across all surfaces
Pill-shaped buttons ({rounded.full}) always
Dark-teal hero bands frame primary CTAs

Known Gaps

Specific dark-mode token values for canvas/surface beyond hero bands not surfaced
Animation/transition timings not extracted; recommend 150–200ms ease
Form validation success state not explicitly captured
Course-tile category color mappings are observation-based
