### 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.

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

### Can I use Phantom’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 Phantom’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.

# Phantom Design System

## Overview

Phantom describes itself as: “The self-custodial wallet for trading predictions, perps, and tokens across Solana, Ethereum, Bitcoin, Robinhood, HyperEVM, and more.” The interface is light, built on **Cool Snow (#F5F2FF)** with **Dark Violet (#3C315B)** text, and **Light Indigo (#AB9FF2)** as the main accent.

Type is set in **Phantom**. Headlines run large with tight negative tracking; body text is 16px. Depth comes from soft drop shadows. Corners are mostly 24px.

Measured from [phantom.com](https://phantom.com/) on November 4, 2026 at 1440×900 and 390×844 from 219 rendered elements. Values are computed styles from the live page, not the original source files.

## Colors

The palette has 12 roles.

- **Cool Snow (#F5F2FF):** Page background, seen 1 time. Token `background`, CSS `--eofi4s0`.
- **Dark Violet (#3C315B):** Primary text and headings, seen 36 times. Token `on-surface`, CSS `--eofi4so`.
- **Charcoal (#1C1C1C):** Headings and emphasis, seen 6 times. Token `on-surface-strong`, CSS `--eofi4s6`.
- **Cool Gray (#86848D):** Secondary text, seen 4 times. Token `on-surface-variant`, CSS `--eofi4s5`.
- **Mist (#F4F2F4):** Raised areas one step from the page, seen 1 time. Token `surface-container-low`, CSS `--eofi4s1`.
- **Snow (#FDFCFE):** Cards and panels, seen 3 times. Token `surface-container`, CSS `--eofi4se`.
- **Warm Snow (#FFFDF8):** Hover and pressed fills, seen 1 time. Token `surface-container-high`, CSS `--eofi4s8`.
- **Mist (#E9E8EA):** Highest raised elements, seen 2 times. Token `surface-container-highest`.
- **Light Indigo (#AB9FF2):** Primary buttons and calls to action, seen 2 times. Token `primary`, CSS `--eofi4s9`.
- **Dark Violet (#3C315B):** Text and icons on primary. Token `on-primary`.
- **Dark Blue (#193A70):** Accent in logos and imagery. Token `secondary`.
- **Dark Amber (#785E19):** Accent in logos and imagery. Token `tertiary`.

## Typography

**Phantom** carries the whole interface. Fallback stack: `Phantom`.

- **display-hero:** Phantom 96px at weight 400, line height 1.1, tracking -0.025em (32px on mobile). Oversized hero statements.
- **headline-display:** Phantom 80px at weight 400, line height 1.1, tracking -0.025em (29px on mobile). Page title (h1).
- **body-md:** Phantom 16px at weight 400. Body text.
- **body-lg:** Phantom 30px at weight 400, line height 1.2. Lead paragraphs.

## Layout

Spacing is mostly on a 4px grid (86% of measured values), with some off-grid steps. Match the measured scale rather than rounding everything.

- **Scale:** xs 4px, sm 8px, md 10px, lg 32px, xl 48px.
- **Sections:** 96px vertical padding between major sections.
- **Gaps:** 10px is the most common gap in flex and grid layouts.
- **Breakpoints:** 639px, 640px, 767px, 768px, 1023px, 1024px, 1279px, 1280px, 1535px, 1536px.

## Elevation & Depth

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

- `rgb(226, 223, 254) 0px 0px 4px 0px`

## Shapes

Most elements use 24px corners. Measured radii, most used first:

- **sm (24px):** 48 elements.
- **md (32px):** 28 elements.
- **full (9999px):** 12 elements.
- **lg (96px):** 8 elements.
- **xl (100px):** 8 elements.
- **xs (4px):** 4 elements.

## Components

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

- **button-primary (“Download”):** #AB9FF2 fill, #3C315B text, 16px/400, 32px radius, padding 16px 32px.
- **button-outline (“Download Phantom”):** #E2DFFE fill, #3C315B text, 13.3333px/400, 96px radius, padding 32px.
- **button-ghost (“Search”):** #FDFCFE fill, #3C315B text, 13.3333px/400, 32px radius, padding 16px.
- **input-field (“Enter your email”):** transparent fill, #3C315B text, 64px/400, padding 0px.
- **link:** transparent fill, #3C315B text, padding 0px.

## Do's and Don'ts

- Do use #F5F2FF for the page and lift surfaces in small steps: #F4F2F4, #FDFCFE, #FFFDF8, #E9E8EA.
- Do keep text in 3 levels: #3C315B, #1C1C1C, #86848D.
- Do reserve #AB9FF2 for primary actions and key highlights.
- Do set headlines in Phantom with tight tracking (-0.025em).
- Do reuse the measured spacing steps (8px, 10px, 32px).
- Do use 24px corners on most elements; larger surfaces also use 32px, 96px and 100px.
- Don't use #86848D for body text; it reaches 3.34:1 on #F5F2FF. Keep it for large text or metadata.
- Don't introduce new font families beyond Phantom.
- Don't use #AB9FF2 for large backgrounds or body text.
- Don't make interface transitions slower than 0.4s.

## Motion

Interface transitions are quick: 0.4s, 0.3s.

- **Easing:** `cubic-bezier(0.22, 1, 0.36, 1)`, `ease`.
- **Reduced motion:** the page responds to `prefers-reduced-motion`.
