Decoded design system

LlamaIndex's decoded design system: background #FFFFFF, text #000000, accent #000000, link #5F5F5F, primary #0000EE; type scale h1 79px / h2 63px / body 16px; 8px spacing base; 8px base radius. The single interactive/action color is #FFFFFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #FFFFFF — the single interactive color; only on things you click or must notice, never large fills.
• accent #000000 — accent for emphasis — keep it rare on the page.
• primary #0000EE — a brand color — but the call-to-action uses #FFFFFF, not this.
• link #5F5F5F — reads as a neutral UI color, not a link accent — verify against the reference (action = #FFFFFF).
• secondary #FFC0CB — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.

Typography

Motion

Micro-interactions run at 75ms (dominant) with ease.

Native design tokens

…and 66 more measured on the page.

Button states (measured)

• common grid: 3 columns

Motion choreography (measured)

Load order: a.AnnouncementBar → a.AnnouncementBar → div.LogosGroup×4 → div.LogosGroup×2

# LlamaIndex — Design System

> light, modern, medium, custom — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#0000EE` |
| accent | `#000000` |
| link | `#5F5F5F` |
| secondary | `#FFC0CB` |
| button_bg | `#FFFFFF` |
| button_text | `#000000` |

**Using these colors**

- **Action color** `#FFFFFF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- **accent** `#000000` — accent for emphasis — keep it rare on the page.
- **primary** `#0000EE` — a brand color — but the call-to-action uses #FFFFFF, not this.
- **link** `#5F5F5F` — reads as a neutral UI color, not a link accent — verify against the reference (action = #FFFFFF).
- **secondary** `#FFC0CB` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 59.2% · `#B5B2E2` 15.6% · `#FBA67A` 9.5% · `#FCA6CC` 6.2%

## Typography

- Heading: **Inter**
- Body: **Inter**
- Mono: **IBMPlexMono**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 79px / 500 · lh 87px · tracking -2.36px |
| h2 | 63px / 500 · lh 69px · tracking -1.88px |
| h3 | 55px / 500 · lh 60px · tracking -1.64px |
| body | 16px / 500 |
| small | 14px / 400 |
| eyebrow | 12px / 400 · tracking 0.48px |

- Weight ladder: 400 · 500 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Inter — free, on Google.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 6px, 8px, 12px, 13px, 14px, 16px, 20px, 24px, 32px, 40px — snap all gaps/padding to these
- section rhythm: 100px top/bottom padding per section (measured)

## Radius
- base: 8px
- button: 0px
- card: 12px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `#000000` | 1px solid rgb(231, 231, 231) | 0px | 8px 24px 8px 24px | 400 12px / 0.48px | none |
| secondary | `#FFFFFF` / `#000000` | none | 0px | — | — | none |

**States (measured, not guessed)**

- primary hover: background `#E7E7E7`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- transition: `background 0.075s ease`

## Motion
- durations: 75ms (dominant) · 350ms · 150ms
- easings: `ease` (dominant) · `ease-out`
- animated properties: background, color, opacity, transform

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

## Their own tokens (verbatim from :root)

_…and 64 more measured on the page._

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- container max 700px · common grid: 3-col
- nav: 52px sticky · bg #FFFFFF

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 110 | 1552 | 3 | — | 48/48 | 3/94/3 |
| 1662 | 1501 | 3 | — | 0/0 | 3/94/3 |
| 3164 | 191 | 3 | — | 0/0 | 3/94/3 |

| 4427 | 1435 | 3 | — | 0/0 | 3/94/3 |

## Motion choreography (measured)
Load order: `a.AnnouncementBar` @0ms → `a.AnnouncementBar` @0ms → `div.LogosGroup`×4 @95ms → `div.LogosGroup`×2 @95ms
- scroll reveal: 9 elements rest at opacity 0, translateY(65px), animate in over 0.35s ease-out (5 revealed during the drive).

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- link: #F5F5F5 · no underline

## Responsive (measured)
- breakpoints: 400px · 500px · 600px · 700px · 768px · 800px
- mobile (390px): hero 33px · body 16px · nav: inline

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
