Decoded design system

Retool's decoded design system: background #151515, text #E9EBDF, accent #E9EBDF, link #CBCCC4, primary #518DD2; type scale h1 72px / h2 48px / body 16px; 4px spacing base; 8px base radius. The single interactive/action color is #E9EBDF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #E9EBDF — the single interactive color; only on things you click or must notice, never large fills.
• accent, button_bg are all #E9EBDF — one role, not several (the action color).
• accent #E9EBDF — 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 #518DD2 — a brand color — but the call-to-action uses #E9EBDF, not this.
• link #CBCCC4 — reads as a neutral UI color, not a link accent — verify against the reference (action = #E9EBDF).
• secondary #003366 — 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.

# Retool — Design System

> dark, modern, high, tailwind — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#151515` |
| surface | `#212121` |
| border | `#343533` |
| text | `#E9EBDF` |
| text_muted | `#989992` |
| primary | `#518DD2` |

| link | `#CBCCC4` |
| secondary | `#003366` |
| button_bg | `#E9EBDF` |
| button_text | `#151515` |

**Using these colors**

- **Action color** `#E9EBDF` — 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 `#E9EBDF` — one role, not several (your action color).
- **accent** `#E9EBDF` — 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** `#518DD2` — a brand color — but the call-to-action uses #E9EBDF, not this.
- **link** `#CBCCC4` — reads as a neutral UI color, not a link accent — verify against the reference (action = #E9EBDF).
- **secondary** `#003366` — 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): `#151515` 52.7% · `#2A2F39` 20.5% · `#6C6D7A` 14.2% · `#DADBD6` 12.6%

## Typography

- Heading: **saansFont** _(free fallback: Newsreader)_
- Body: **saansFont** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 72px / 300 · lh 76px · tracking -1.58px |
| h2 | 48px / 300 · lh 50px · tracking -0.48px |
| h3 | 24px / 380 · lh 29px · tracking -0.24px |
| body | 16px / 300 · lh 24px · tracking 0.16px |
| small | 14px / 400 · lh 17px · tracking 0.14px |

- Weight ladder: 300 · 380 · 400 — use these exact measured weights, not the 400/600 defaults.

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

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 12px, 14px, 16px, 20px, 24px, 32px — snap all gaps/padding to these
- section rhythm: 40px top/bottom padding per section (measured)

## Radius
- base: 8px
- button: 9999px
- card: 4px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#E9EBDF` / `#151515` | none | 9999px | 0px 20px 0px 20px | 400 14px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#E9EBDF` | 1px solid rgb(139, 134, 127) | 9999px | 0px 20px 0px 20px | 400 14px | none |

**States (measured, not guessed)**

- primary hover: background `#FFFFFF`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: border `1px solid rgb(67, 62, 56)`
- transition: `color 0.3s cubic-bezier(0.72, 0, 0.12, 1)`

## Shadows (elevation)
- subtle: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.35) 0px 68px 116px 0px`
- card: `rgba(0, 0, 0, 0.12) 0px 1px 2px 0px, rgb(0, 0, 0) 0px 0px 0px 0.5px`

## Motion
- durations: 300ms (dominant) · 400ms · 600ms
- easings: `ease` (dominant) · `cubic-bezier(0.72, 0, 0.12, 1)`
- animated properties: opacity, transform, border-color, color

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

## Motion choreography (measured)
Load order: `div.absolute`×2 @0ms → `div.absolute` @0ms → `div.flex`×2 @0ms → `div.text-surface-text-muted`×2 @409ms → `div.relative` @1427ms → `div.absolute` @1427ms

- scroll reveal: 3 elements rest at opacity 0, animate in over 0.5s cubic-bezier(0.72, 0, 0.36, 1) (1 revealed during the drive).
- overlay dialog (auto-opened): panel rgba(247, 248, 244, 0.867) · r 16px · border 1px solid rgba(21, 21, 21, 0.12) · shadow rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0.1) 0px 20px 25px -5px, rgba(0, 0, 0, 0.1) 0px 8px 10px -6px

  - exit: opacity from 0.99987 · 200ms cubic-bezier(0.72, 0, 0.12, 1)

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

## 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.
