MongoDB

MongoDB Inc. (NASDAQ: MDB) is the company behind the document- oriented NoSQL database of the same name and MongoDB Atlas, the managed cloud database that runs across AWS, Google Cloud, and Azure. The brand voice is technical, builder-friendly, and unmistakably green: MongoDB Green (#00ED64) is the vivid signature, the "leaf" mark color, and the wordmark accent. MongoDB Black is a documented blue-black (#001E2B), not pure black — it serves as the dark-mode canvas, the dark wordmark, and the primary text color on light surfaces. The design system that backs MongoDB Atlas and Compass is LeafyGreen UI, the open-source React library that publishes the palette mirrored here. The proprietary typeface is Euclid Circular (with MongoDB-branded customizations); it is not publicly licensed, so this atom references Inter as the open rendering substitute.

Palette

MongoDB · [email protected] · Apache-2.0

MongoDB's design-token palette, sourced from the open-source LeafyGreen UI library (mongodb/leafygreen-ui) — the React component library and design system that backs MongoDB Atlas, Compass, the MongoDB.com marketing surface, and the documentation portal. The palette is anchored on MongoDB Green (#00ED64, the brand-defining signature) and a deep MongoDB Black (#001E2B, a blue-black canvas color, NOT pure black). Six chromatic families (Green, Blue, Yellow, Red, Purple, plus Gray) each ship in a base value with light1/light2/light3 and dark1/dark2/dark3 variants — the "base" is the canonical brand stop, lighter for backgrounds, darker for text/contrast.

Rules

🛑 error (8)

colorChoiceroles.colors.mark

  • allowed: green-base, green-dark1, green-dark2, white, black
  • forbidden: blue-base, red-base, yellow-base, purple-base

The MongoDB leaf mark renders in Green base on dark canvases, Green Dark 1 or Dark 2 where contrast against light surfaces is required, or in solid white / solid black for monochrome treatments. Recoloring the leaf to blue, red, yellow, or purple violates MongoDB's documented brand-mark usage.

colorChoiceroles.colors.primary

  • allowed: green-dark2, green-dark3, green-dark1, green-base
  • forbidden: blue-base, red-base, purple-base, yellow-base

MongoDB's primary interactive color is documented as Green Dark 2 (#00684A) on light surfaces and Green base (#00ED64) on dark surfaces. The other chromatic base swatches are reserved for semantic and data-viz roles.

contrastRatiotext-primary

  • against: background
  • minRatio: 4.5
  • standard: WCAG-AA

LeafyGreen UI's published accessibility commitment targets WCAG 2.1 AA. MongoDB Black (#001E2B) on white clears AA at ~17:1; Gray Light 2 (#E8EDEB) on Black clears AA at ~14:1 — both modes' primary text/background pairs satisfy the floor.

forbiddenTreatmentlogo

  • treatments: stretched, rotated, recolored, drop-shadow, gradient-fill, outlined, on-busy-photo, tilted

MongoDB's brand-resource guidelines prohibit stretching, rotating, recoloring, outlining, adding shadows, or applying decorative effects to the leaf mark and wordmark. The wordmark renders in Black on light surfaces and White on dark surfaces; the leaf renders in Green base or in the documented monochrome variants only.

contextRestrictionroles.colors.accent

  • forbiddenContexts: body-text, small-text
  • allowedContexts: brand-block, hero, cta, data-viz-positive, illustration

MongoDB Green base (#00ED64) is intentionally vivid and does NOT clear WCAG AA for body or small-text use against white. It is the brand accent for hero blocks, CTAs at button-text size, and illustration — not for paragraph or fine-print copy. Use Green Dark 2 for accessible text-weight uses.

contextRestrictionroles.colors.identity

  • forbiddenContexts: product-of-competitor, merchandise, endorsement-implication, company-name-or-domain

MongoDB's trademark guidance forbids using the MongoDB name, the leaf mark, or the green-on-black brand treatment in third-party company names, domains, merchandise, or any context that implies affiliation or endorsement.

fontPairingtypography.display

  • requires: prose
  • minSizeRatio: 1.5

MongoDB's marketing and product surfaces maintain at least a 1.5× ratio between heading and body to preserve the type hierarchy LeafyGreen components depend on for scannability on dense data surfaces (Atlas dashboards, Compass).

accessibilityRequirement*

  • standard: WCAG-AA
  • criterion: 1.4.3

WCAG 2.1 Success Criterion 1.4.3 (Contrast Minimum) — Level AA. LeafyGreen UI's published accessibility commitment treats AA as the floor for every MongoDB-branded component and the tokens that back them.

⚠️ warning (1)

enumMembershiptypography.heading.fontWeight

  • allowed: 400, 500, 600, 700

LeafyGreen UI's documented type ramp anchors on Regular (400), Medium (500), Semibold (600), and Bold (700) — the weights Euclid Circular and the documented sans substitute both ship. Lighter or heavier display cuts are not part of the defined system ramp.

💡 recommendation (1)

compositionConstraintroles.colors.mark

  • pairsWith: black, white, gray-light3, gray-dark3
  • doesNotPairWith: red-base, purple-base, yellow-base

MongoDB Green is calibrated to read on the brand black canvas, on white, and on the documented neutral light/dark surfaces. Placing it adjacent to red-base, purple-base, or yellow-base at equal weight produces chromatic conflict and breaks the confident, builder-focused voice of the brand surface.

  • Notes: MongoDB Green base (#00ED64) is the vivid brand accent but does NOT clear WCAG AA against white at typical text sizes; the primary interactive role on light surfaces resolves to Green Dark 2 (#00684A) — the AA-readable variant LeafyGreen uses for buttons and links — while Green base carries the role on dark surfaces and on hero/identity blocks. Euclid Circular is not publicly licensed; Inter is referenced as the rendering substitute for sans (heading, body).

Components — same template, themed by MongoDB

Every block below renders from the resolved palette + font references on this brand. Swap the brand and the same template re-themes — no per-brand component code required.

MongoDB

A clear hierarchy in MongoDB's typeface

Tertiary heading — supporting structure

Body copy renders in the brand's prose font on the brand's background. Inline links and highlighted phrases pick up the brand's primary and highlight roles. Code spans like brand.references.palette fall back to the monospace face.

A blockquote uses the brand's accent color as its rule. Useful for pulling tagline copy out of running prose.
Bulleted list
  • Bullet markers inherit the brand's primary color.
  • Item spacing reads as a deliberate vertical rhythm.
  • Nested items still resolve to the same primary.
    • Second-level item using the accent.
    • Third bullet wraps cleanly at narrow widths.

Neutral status — provides supplemental context without urgency. Uses the brand's primary as the rule.

Success

Confirms a completed action — palette role success determines the rule color.

Warning

Calls out something that needs attention but isn't an error — palette role warning.

Error

Surfaces a failure that blocks progress — palette role error. Use sparingly.
