Rules written from the measurements, so a coding agent stays on style.

Use #EEEEEE for the page and lift surfaces in small steps: #FFFFFF, #CCCCCC.
Keep text in 3 levels: #555555, #666666, #777777.
Reserve #3C78B4 for primary actions and key highlights.
Reuse the measured spacing steps (8px, 9.6px, 20px).
Use 3px corners on most elements.
Use #777777 for body text; it reaches 3.86:1 on #EEEEEE. Keep it for large text or metadata.
Introduce new font families beyond Lato.
Use #3C78B4 for large backgrounds or body text.
Make interface transitions slower than 0.15s.

# Sublime Text Design System

## Overview

Sublime Text describes itself as: “Sublime Text is a sophisticated text editor for code, markup and prose. You'll love the slick user interface, extraordinary features and amazing performance.” The interface is light, built on **Mist (#EEEEEE)** with **Slate (#555555)** text, and **Blue (#3C78B4)** as the main accent.

Type is set in **Lato**. Headlines run large; body text is 16px. Depth comes from soft drop shadows. Corners are mostly 3px.

Measured from [sublimetext.com](https://www.sublimetext.com/) on November 4, 2026 at 1440×900 and 390×844 from 87 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 14 roles.

- **Mist (#EEEEEE):** Page background, seen 1 time. Token `background`.
- **Slate (#555555):** Primary text and headings, seen 13 times. Token `on-surface`.
- **Slate (#666666):** Secondary text, seen 5 times. Token `on-surface-variant`.
- **Slate (#777777):** Muted text and metadata, seen 10 times. Token `on-surface-muted`.
- **White (#FFFFFF):** Raised areas one step from the page, seen 5 times. Token `surface-container-low`.
- **Silver (#CCCCCC):** Cards and panels, seen 3 times. Token `surface-container`.
- **Mist 80% (#EEEEEECC):** Translucent fill for cards and controls, seen 3 times. Token `overlay`.
- **Silver 80% (#CCCCCCCC):** Stronger translucent fill, seen 2 times. Token `overlay-strong`.
- **Silver (#CCCCCC):** Borders and dividers, seen 5 times. Token `outline`.
- **Blue (#3C78B4):** Primary buttons and calls to action, seen 4 times. Token `primary`.
- **White (#FFFFFF):** Text and icons on primary. Token `on-primary`.
- **Gray (#888888):** High-contrast fills, seen 1 time. Token `inverse-surface`.
- **Blue (#157BBC):** Accent, seen 1 time. Token `secondary`.
- **Blue (#4075BF):** Inline links, seen 2 times. Token `link`.

## Typography

**Lato** carries the whole interface. Fallback stack: `Lato, Arial, sans-serif`.

- **headline-display:** Lato 48px at weight 400, line height 1.6 (30px on mobile). Page title (h1).
- **headline-lg:** Lato 32px at weight 700, line height 1.6. Section headings (h2).
- **headline-md:** Lato 24px at weight 400, line height 1.6, tracking 0.021em, uppercase. Sub-section headings.
- **body-md:** Lato 16px at weight 400, line height 1.6. Body text.
- **body-sm:** Lato 14.5px at weight 400, line height 1.6. Secondary and small text.
- **caption:** Lato 13px at weight 400, line height 1.6. Captions and fine print.

## Layout

Spacing does not follow a strict grid: 50% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.

- **Scale:** xs 2px, sm 8px, md 9.6px, lg 20px, xl 40px.
- **Container:** content is capped at 1200px.
- **Breakpoints:** 550px, 640px, 700px, 820px, 1000px, 1024px, 1100px, 1140px, 1160px, 1200px, 1240px.

## Elevation & Depth

Raised elements use soft drop shadows. The most used recipes:

- `rgba(0, 0, 0, 0.08) 0px 0px 20px 0px`
- `rgba(58, 58, 58, 0.3) 1px 1px 5px 0px`

## Shapes

Most elements use 3px corners. Measured radii, most used first:

- **md (3px):** 72 elements.

## Components

Measured from the rendered page. Token values reference the tokens above.

- **button-primary (“INSTALL FOR LINUX”):** #3C78B4 fill, #FFFFFF text, 16px/400, 3px radius, padding 8px 15px.
- **button-primary-hover:** background #336699, text #FFFFFF on hover.
- **button-ghost (“Pause”):** transparent fill, #999999 text, 14.4px/400, padding 2px 4px.
- **card:** #FFFFFF fill, #555555 text, 16px/400, 4px radius, padding 16px, shadow `rgba(58, 58, 58, 0.3) 1px 1px 5px 0px`.
- **link:** transparent fill, #4075BF text, padding 0px.

## Do's and Don'ts

- Do use #EEEEEE for the page and lift surfaces in small steps: #FFFFFF, #CCCCCC.
- Do keep text in 3 levels: #555555, #666666, #777777.
- Do reserve #3C78B4 for primary actions and key highlights.
- Do reuse the measured spacing steps (8px, 9.6px, 20px).
- Do use 3px corners on most elements.
- Don't use #777777 for body text; it reaches 3.86:1 on #EEEEEE. Keep it for large text or metadata.
- Don't introduce new font families beyond Lato.
- Don't use #3C78B4 for large backgrounds or body text.
- Don't make interface transitions slower than 0.15s.

## Motion

Interface transitions are quick: 0.15s.

- **Easing:** `ease-in-out`.

No. Sitepeel measured it from sublimetext.com’s public page on November 4, 2026. It is an independent analysis, not made or approved by Sublime Text.

Can I use Sublime Text’s style in my own product?

Use it to learn, prototype and compare. For a real product, make the style your own, and never copy Sublime Text’s logo, name, pictures or text.

How accurate are the values?

Each value was measured on the rendered page after it fully loaded, on desktop and mobile: colors where they appear, type with tracking, spacing, corners, shadows and hover states. Sites change, so check the date at the top.
