Do’s and don’ts
Rules written from the measurements, so a coding agent stays on style.
- Use #061217 for the page and lift surfaces in small steps: #0B191B, #000000, #0E1F22, #112529.
- Keep text in 4 levels: #FFFFFF, #C8FFD9, #6B8176, #536F74.
- Reserve #5EFF88 for primary actions and key highlights.
- Set headlines in fk-grotesk-light with tight tracking (-0.04em).
- Reuse the measured spacing steps (7px, 15px, 24px).
- Use 16px corners on most elements; larger surfaces also use 26.3px, 32px and 3.75px.
- Use #536F74 for body text; it reaches 3.52:1 on #061217. Keep it for large text or metadata.
- Add drop shadows for depth; use tonal surfaces.
- Introduce new font families beyond fk-grotesk-light, fk-display, fk-grotesk-regular, sans-serif and fk-grotesk-mono-medium.
- Use #5EFF88 for large backgrounds or body text.
- Make interface transitions slower than 0.5s.

# Ethiack Design System
## Overview
Ethiack describes itself as: “Ethiack is the Adversarial Exposure Validation platform. Hackian continuously tests your attack surface, validates exploitability with proof-of-exploit, and eliminates 90% of scanner noise. See your exposure. Test contin” The interface is dark, built on **Cool Charcoal (#061217)** with **White (#FFFFFF)** text, and **Green (#5EFF88)** as the main accent.
Type is set in **fk-grotesk-light** and **fk-display**, with **fk-grotesk-mono-medium** for code. Headlines run large with tight negative tracking; body text is 15px. The surface language is flat. Corners are mostly 16px.
Measured from [ethiack.com](https://ethiack.com/) on November 7, 2026 at 1440×900 and 390×844 from 374 rendered elements. Values are computed styles from the live page, not the original source files.
## Colors
The palette has 15 roles.
- **Cool Charcoal (#061217):** Page background, seen 2 times. Token `background`, CSS `--color-deep-green-800`.
- **White (#FFFFFF):** Primary text and headings, seen 29 times. Token `on-surface`, CSS `--color-geral-white`.
- **Pale Green (#C8FFD9):** Secondary text, seen 2 times. Token `on-surface-variant`, CSS `--color-bright-green-100`.
- **Slate (#6B8176):** Muted text and metadata, seen 6 times. Token `on-surface-muted`, CSS `--color-muted-green-400`.
- **Cyan (#536F74):** Subtle text and placeholders, seen 2 times. Token `on-surface-subtle`, CSS `--color-light-grey-800`.
- **Cool Charcoal (#0B191B):** Raised areas one step from the page, seen 1 time. Token `surface-container-low`, CSS `--color-deep-green-700`.
- **Near Black (#000000):** Cards and panels, seen 5 times. Token `surface-container`.
- **Deep Cyan (#0E1F22):** Hover and pressed fills, seen 3 times. Token `surface-container-high`, CSS `--color-deep-green-600`.
- **Deep Cyan (#112529):** Highest raised elements, seen 1 time. Token `surface-container-highest`, CSS `--color-deep-green-500`.
- **Cyan 20% (#536F7433):** Borders and dividers, seen 4 times. Token `outline`.
- **Near Black (#000000):** Secondary dividers, seen 2 times. Token `outline-variant`.
- **Green (#5EFF88):** Most used accent color, seen 16 times. Token `primary`.
- **Near Black (#000000):** Text and icons on primary. Token `on-primary`.
- **Vivid Red (#FF0015):** Errors and destructive states, seen 3 times. Token `error`, CSS `--color-infection-detected`.
- **Light Green (#98FEB8):** Success and positive states, seen 1 time. Token `success`.
## Typography
**fk-grotesk-light**, **fk-display**, **fk-grotesk-regular**, **sans-serif** and **fk-grotesk-mono-medium** (monospace) share the interface. Fallback stack: `fk-grotesk-light`. Other loaded fonts: fk-grotesk-medium, fk-grotesk-mono, fk-raster-blended, fk-raster-rounded.
- **headline-display:** fk-grotesk-light 58px at weight 400, line height 1, tracking -0.04em (36px on mobile). Page title (h1).
- **headline-lg:** fk-display 43px at weight 400, line height 0.9, tracking -0.02em. Section headings (h2).
- **headline-md:** fk-grotesk-light 33.5px at weight 400, line height 1.1, tracking -0.03em (24px on mobile). Sub-section headings.
- **headline-sm:** fk-grotesk-regular 23px at weight 400, line height 1.1, tracking -0.04em (18px on mobile). Card and feature titles.
- **body-md:** sans-serif 15px at weight 400, line height 1.6, tracking 0.007em. Body text.
- **body-lg:** fk-grotesk-regular 18px at weight 400, line height 1.3, tracking -0.01em. Lead paragraphs.
- **body-sm:** fk-grotesk-regular 14px at weight 400, line height 1.1, tracking -0.01em. Secondary and small text.
- **caption:** fk-grotesk-regular 12px at weight 400, line height 1.1. Captions and fine print.
- **label-md:** sans-serif 16px at weight 400, line height 1. Buttons, navigation and labels.
- **label-sm:** sans-serif 15px at weight 600, line height 1.6, tracking 0.007em. Small labels and badges.
- **code:** fk-grotesk-mono-medium 10px at weight 400, line height 1, uppercase. Code and technical values.
## Layout
Spacing does not follow a strict grid: 34% of measured values are multiples of 4px, so match the measured steps rather than rounding to a grid.
- **Scale:** xs 4px, sm 7px, md 15px, lg 24px, xl 48px.
- **Gaps:** 24px is the most common gap in flex and grid layouts.
- **Breakpoints:** 400px, 410px, 743px, 1023px, 1290px, 1440px, 1700px, 2000px.
## Elevation & Depth
The design is flat: no shadows were measured. Hierarchy comes from tonal surface steps (#0B191B → #000000 → #0E1F22 → #112529) and #536F7433 borders.
## Shapes
Most elements use 16px corners. Measured radii, most used first:
- **md (16px):** 84 elements.
- **lg (26.3px):** 20 elements.
- **xl (32px):** 16 elements.
- **xs (3.75px):** 12 elements.
- **sm (9px):** 12 elements.
## Components
Measured from the rendered page. Token values reference the tokens above.
- **button-outline (“Subscribe Newsletter”):** #112529 fill, #C8FFD9CC text, 12px/400, 16px radius, padding 0px 14px.
- **link:** transparent fill, #112529 text, padding 0px.
## Do's and Don'ts
- Do use #061217 for the page and lift surfaces in small steps: #0B191B, #000000, #0E1F22, #112529.
- Do keep text in 4 levels: #FFFFFF, #C8FFD9, #6B8176, #536F74.
- Do reserve #5EFF88 for primary actions and key highlights.
- Do set headlines in fk-grotesk-light with tight tracking (-0.04em).
- Do reuse the measured spacing steps (7px, 15px, 24px).
- Do use 16px corners on most elements; larger surfaces also use 26.3px, 32px and 3.75px.
- Don't use #536F74 for body text; it reaches 3.52:1 on #061217. Keep it for large text or metadata.
- Don't add drop shadows for depth; use tonal surfaces.
- Don't introduce new font families beyond fk-grotesk-light, fk-display, fk-grotesk-regular, sans-serif and fk-grotesk-mono-medium.
- Don't use #5EFF88 for large backgrounds or body text.
- Don't make interface transitions slower than 0.5s.
## Motion
Interface transitions are quick: 0.5s, 0.3s, 0.25s, 0.4s.
- **Easing:** `cubic-bezier(0.23, 1, 0.32, 1)`, `cubic-bezier(0.645, 0.045, 0.355, 1)`, `cubic-bezier(0.19, 1, 0.22, 1)`.

What is the Ethiack DESIGN.md?
A plain-text file with Ethiack’s measured colors, type, spacing, corners and components as tokens, plus short rules, in the DESIGN.md format Google published with Stitch. Your AI coding agent reads it and builds in this style. More about DESIGN.md.
How do I use it with Claude Code or Cursor?
Download the file and put it in your project’s root folder, then ask your agent to follow DESIGN.md. Step-by-step guides: Claude Code, Cursor, Codex, GitHub Copilot.
Is this Ethiack’s official design system?
No. Sitepeel measured it from ethiack.com’s public page on November 7, 2026. It is an independent analysis, not made or approved by Ethiack.
Can I use Ethiack’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 Ethiack’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.
