OneContext Brand Guidelines
Overview
OneContext is the universal AI identity platform. Our visual identity is clean, minimal, and functional—predominantly white with dark green used sparingly as a strategic accent. Prioritize infrastructure-grade reliability over consumer-app flashiness.
Keywords: OneContext brand, visual identity, UI styling, colors, typography, developer-first design, Tailwind, shadcn

For tone, voice, and copy (headlines, CTAs, landing text, docs, social), use the brand-copy-guidelines skill.
Color System
Primary
- Base: White
#FFFFFF – dominant for backgrounds, forms, cards. The brand is intentionally minimal with lots of white space.
- Primary accent: Dark Green
#047857 (Tailwind emerald-700) – CTAs, links, active states, badges, key highlights. Use sparingly, not as broad fill.
- Hover / focus: Lighter Green
#10B981 (Tailwind emerald-500) – hover states, subtle highlights, focus rings.
Neutrals & Semantic
- Neutrals: Tailwind gray scale (50–950).
- Text (light mode): Gray-900.
- Text (dark mode): Gray-50.
- Dark backgrounds: Near-black
#0A0A0A / #18181B.
- Error: Red
#EF4444.
- Warning: Amber
#F59E0B.
Rule: The brand is not green-heavy. Green only for interactive/important elements.
Typography
- Primary font: Inter or Geist (open license). Use in web/app; fallback: system sans-serif.
- Code / mono: Geist Mono, JetBrains Mono, or Fira Code for code, keys, CLIs.
Hierarchy
| Element | Size | Weight |
|---|
| H1 Hero | 48–64px | Bold |
| H2 | 36–40px | Semibold |
| H3 | 24–28px | — |
| Body | 16–18px | Regular (line-height 1.6–1.7) |
| Small/caption | 14px | — |
UI Component Patterns
- Buttons: Rounded 6–8px. Primary CTA = dark green; hover/focus = lighter green. Accessible contrast.
- Cards: White, gray border or subtle shadow, padded, clearly labeled.
- Forms: Labels above fields, inline validation.
- Status: Color-coded; icon + text; dark green for success/active.
- Code blocks: Dark theme, syntax highlighting, copy button.
- Navigation: White base; dark green underline or fill for active; mobile-responsive.
- Spacing: 8px grid; generous whitespace.
- Shadows: Subtle, only where elevation is needed.
Iconography
- Style: Lucide or Heroicons; line-based, 24px, 1.5–2px stroke.
- Use dark green only for accent or active indicators—never as broad icon fill.
- Consistent size and color per context (sync, link, key, check, close, settings, code, user).
Motion
- Reserved and fast; indicate state change, not decoration.
- Hover: ~100–150ms (e.g. green → lighter green on buttons).
- Transitions: 200–300ms; complex: 400–500ms.
- Sync in progress: spinning icon, <1s loop. Page transitions: fast fade/slide <200ms.
Technical Integration
- Tailwind: Use tokens from project config (
white, emerald-700, emerald-500, grays, reds, ambers).
- Components: shadcn/ui; Lucide icons; Inter (or Geist) font.
- Assets: Logo/icon/wordmark in
/public/brand/ (SVG primary, PNG for social); monochrome for dark/accessibility.
- Accessibility: Minimum WCAG AA contrast; focus indicators on all interactive elements; support light and dark backgrounds.
When creating or editing UI, marketing pages, or docs, apply these colors, type scale, and patterns so OneContext stays consistent and on-brand.
