Fal — Design System

light · modern · medium · tailwind · confidence 90% · deep decode

fal runs inference at display scale: Focal at 120px/500 in black on white ('Generative media platform for developers.'), 16px body, and near-square 2px-radius ink buttons. Model cards and latency numbers grid out beneath — a GPU platform whose page is as fast-loading and unadorned as the diffusion endpoints it sells.

Tokens

Fal's decoded design system: background #FFFFFF, text #000000, accent #252527, link #F3E8FF, primary #99EDFF; type scale h1 120px / h2 24px / body 18px; 8px spacing base; 4px base radius. The single interactive/action color is #252527 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

# Fal — Design System

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

fal runs inference at display scale: Focal at 120px/500 in black on white ('Generative media platform for developers.'), 16px body, and near-square 2px-radius ink buttons. Model cards and latency numbers grid out beneath — a GPU platform whose page is as fast-loading and unadorned as the diffusion endpoints it sells.

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#EFEFEF` |
| border | `#D8D8D8` |
| text | `#000000` |
| text_muted | `#606060` |
| primary | `#99EDFF` |
| accent | `#252527` |
| link | `#F3E8FF` |
| secondary | `#F1FFD2` |
| button_bg | `#252527` |
| button_text | `#FAFAFA` |

**Using these colors**

- **Action color** `#252527` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `button_bg` are all `#252527` — one role, not several (your action color).
- **accent** `#252527` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **primary** `#99EDFF` — a brand color — but the call-to-action uses #252527, not this.
- **link** `#F3E8FF` — fails contrast on the background (~1.2:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#F1FFD2` — 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): `#99ECFF` 63.6% · `#070A0E` 9.4% · `#FDFDB0` 8.3% · `#50BCD7` 6.5%

## Typography

- Heading: **Focal** _(free fallback: Newsreader)_
- Body: **Public Sans** _(free fallback: Newsreader)_
- Mono: **Chivo Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 120px / 500 · lh 100px · tracking -4.8px |
| h2 | 80px / 500 · lh 70px |
| h3 | 60px / 500 · lh 60px · tracking -2.4px |
| body | 16px / 400 · lh 24px |
| small | 15px / 500 · lh 23px |

- Weight ladder: 400 · 500 · 600 · 700 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Focal may be proprietary — safe free fallback: Newsreader (Google Fonts). Public Sans may be proprietary — safe free fallback: Newsreader (Google Fonts).

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 6px, 8px, 12px, 16px, 20px, 24px, 26px, 32px, 40px — snap all gaps/padding to these

## Radius
- base: 4px
- button: 4px
- card: 4px
- sharp: 2px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#202022` / `#FAFAFA` | 1px solid rgba(0, 0, 0, 0) | 4px | 0px 24px 0px 24px | 600 16px / -0.16px | none |
| secondary | `#FFFFFF` / `#19191A` | 1px solid rgba(25, 25, 26, 0.13) | 4px | 0px 24px 0px 24px | 600 16px / -0.16px | none |

**States (measured, not guessed)**

- primary hover: background `#494950`
- primary focus: box-shadow `rgba(0, 0, 0, 0) 0px 0px 0px 1px, rgb(131, 82, 255) 0px 0px 0px 1px, rgba(0, 0, 0, 0) 0px 0px 0px 0px` · outline `2px solid rgba(0, 0, 0, 0)`
- secondary hover: background `rgba(25, 25, 26, 0.1)`
- transition: `background-color 0.15s cubic-bezier(0.4, 0, 0.2, 1)`

## Motion
- durations: 150ms (dominant) · 75ms · 300ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `cubic-bezier(0.23, 1, 0.32, 1)`
- animated properties: background-color, color, border-color, transform

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

## Layout (measured)
- container max 1200px
- nav: 36px

## Motion choreography (measured)
Load order: `path.pixel-decoration-cell`×8 @0ms → `div.h-64`×2 @210ms
- scroll reveal: 4 elements rest at translateY(89px) (4 revealed during the drive).

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

## Components (measured)
- link: #18181B · underline

## Responsive (measured)
- breakpoints: 480px
- mobile (390px): hero 46px · 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.
