Decoded design system

Appsmith's decoded design system: background #16122E, text #000000, accent #7441F7, link #E8E7EB, primary #190F36; type scale h1 64px / h2 44px / body 18px; 8px spacing base; 4px 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 #7441F7 — accent for emphasis — keep it rare on the page.
• primary #190F36 — a brand color — but the call-to-action uses #FFFFFF, not this.
• link #E8E7EB — reads as a neutral UI color, not a link accent — verify against the reference (action = #FFFFFF).
• secondary #9999A9 — 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.

# Appsmith — Design System

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

## Colors

| Role | Value |
|------|-------|
| bg | `#16122E` |
| surface | `#14102B` |
| border | `#120F27` |
| text | `#000000` |
| text_muted | `#080611` |
| primary | `#190F36` |
| accent | `#7441F7` |
| link | `#E8E7EB` |
| secondary | `#9999A9` |
| button_bg | `#FFFFFF` |
| button_text | `#7441F7` |

**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** `#7441F7` — accent for emphasis — keep it rare on the page.
- **primary** `#190F36` — a brand color — but the call-to-action uses #FFFFFF, not this.
- **link** `#E8E7EB` — reads as a neutral UI color, not a link accent — verify against the reference (action = #FFFFFF).
- **secondary** `#9999A9` — 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` 90% · `#DFD8F2` 5.3% · `#6A53A6` 4.7%

## Typography

- Heading: **Red Hat Display** _(free fallback: Newsreader)_
- Body: **Red Hat Display** _(free fallback: Newsreader)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 64px / 900 · lh 77px |
| h2 | 44px / 700 · lh 55px |
| h3 | 22px / 700 · lh 33px |
| body | 18px / 400 · lh 27px |
| small | 16px / 500 · lh 22px |

- Weight ladder: 400 · 500 · 700 · 900 — use these exact measured weights, not the 400/600 defaults.

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

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 4px, 8px, 10px, 12px, 16px, 24px, 32px, 46px, 48px, 64px — snap all gaps/padding to these
- section rhythm: 48px top/bottom padding per section (measured)

## Radius
- base: 4px
- button: 4px
- card: 6px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `rgba(0, 0, 0, 0)` / `#7441F7` | 1px solid rgb(116, 65, 247) | 4px | 10px 24px 10px 24px | 500 14px | none |
| secondary | `rgba(0, 0, 0, 0)` / `#FFFFFF` | none | 4px | 10px 24px 10px 24px | 500 14px | none |

**States (measured, not guessed)**

- primary hover: background `rgba(116, 65, 247, 0.1)`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: color `#7441F7`
- transition: `color 0.3s cubic-bezier(0.4, 0, 0.2, 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, 0.06) 0px 22px 134px -2px`
- card: `rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgba(0, 0, 0, 0) 0px 0px 0px 0px, rgb(22, 18, 46) 0px 22px 134px -2px`

## Motion
- durations: 300ms (dominant) · 150ms · 1000ms
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant) · `linear`
- animated properties: opacity, color, background-color, border-color

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)

| Token | Value |
|-------|-------|
| `--font-red-hat-display` | `"__redHatDisplay_8edbd5","__redHatDisplay_Fallback_8edbd5"` |
| `--font-red-hat-mono` | `"__redHatMono_81d51a","__redHatMono_Fallback_81d51a"` |
| `--font-tenon` | `"__tenon_cebc3f","__tenon_Fallback_cebc3f"` |

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

## Layout (measured)
- container max 1150px · common grid: 3-col
- nav: 68px sticky · bg #FFFFFF

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 68 | 494 | — | — | 48/48 | — |
| 562 | 598 | — | — | 48/48 | — |
| 1160 | 216 | 3 | — | 24/48 | 67/17/17 |
| 1376 | 205 | — | — | 48/24 | — |

## Motion choreography (measured)
- scroll reveal: 20 elements rest at opacity 0, translateY(-20px), animate in over 0.3s cubic-bezier(0.4, 0, 0.2, 1) (4 revealed during the drive).
- overlay dialog (auto-opened): panel #FFFFFF · r 4px · border 1px solid rgba(231, 230, 234, 0.5) · 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
  - enter: transform+opacity from rotateX(-30deg) scale(0.9),0 · 300ms linear

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

## Responsive (measured)
- breakpoints: 480px · 640px · 768px · 1024px · 1280px · 1536px
- mobile (390px): hero 32px · body 16px · nav: hamburger

## 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.
