Mongodb, in one page

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

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
