# Uniswap — Style Reference
> Fuzzy Neon Playground. Crisp white UI elements float above a swirling background of blurred, vibrant color.

**Theme:** light

**Site:** https://uniswap.org

Uniswap's design system feels like a playful, high-energy data interface, grounded by stark neutrals and then splashed with a vibrant, almost neon palette. The soft, blurry background elements provide a sense of atmospheric depth without heavy shadows or complex textures, creating a digital ether. Type is uniformly monochrome, allowing bold, vivid accents to pop purely through color on interactive elements and data visualizations, drawing the eye instantly to critical information and actions. The overall impression is approachable yet cutting-edge, like a friendly gateway to complex financial technology.

## Layout

The page primarily uses a centered, max-width contained layout for content, but features a full-bleed vibrant blurred background that extends edge-to-edge. The hero section presents a prominent headline over this atmospheric background, followed by a central card-like swap interface. Section rhythm is generally consistent with vertical spacing, often separating content blocks with padding rather than visual dividers. Content elements, such as text and feature callouts, are stacked centrally or arranged in simple, clean two-column layouts. Navigation is a sticky top bar with clearly defined interactive elements, incorporating search and primary actions. The density is comfortable, providing breathing room around key components while still presenting a good amount of information.

## Imagery

The visual language focuses on abstract, blurred, and brightly colored 'blob' shapes that appear to float behind the crisp UI, contributing a sense of ethereal movement and playful energy. These shapes are multi-colored and semi-transparent, creating a soft, luminous background effect that makes the UI elements stand out. Specific icons or illustrations, when present, are often abstract representations of cryptocurrencies or blockchain concepts, using the vibrant color palette. Photography is absent; the emphasis is purely on UI and abstract digital visuals. The treatment is full-bleed for the background effects, while UI components are contained and use soft radii.

## Components

### Swap Interface Card

### Protocol Stats Card

### Button Group Showcase

### Primary Action Button
*Filled button*

backgroundColor: #ff37c7, color: #ffffff, borderRadius: 999999px, paddingTop: 8px, paddingRight: 16px, paddingBottom: 8px, paddingLeft: 16px. Typography: Basel, weight 500, size 16px. Used for main calls to action like 'Connect' and 'Select token'.

### Secondary Ghost Button
*Outlined/Ghost button*

backgroundColor: rgba(0,0,0,0), color: #131313, border: 1px solid #131313, borderRadius: 12px, padding: 0px. Used for secondary navigation items or less emphasized actions. Text color changes to #222222 when interactive.

backgroundColor: rgba(0,0,0,0), color: #131313 or #222222, borderRadius: 12px, padding: 0px. Used for primary navigation items. Emphasis is achieved via color change or active state indicator.

### Swap Input Field
*Financial input*

backgroundColor: #ffffff, color: #131313, border: 1px solid #f2f2f2 (or rgba(0,0,0,0) as default), borderRadius: 20px, padding: 16px. Placeholder text is Ash Gray (#6a6a6a). Contains sub-elements for currency selection.

### Simple Card
*Content container*

backgroundColor: #ffffff, borderRadius: 20px, padding: typically 16px. Used for containing swap interface or other key information blocks. Often has a subtle box-shadow.

### Icon Button
*Interactive icon*

backgroundColor: rgba(0,0,0,0), color: #131313 (default icon color), padding: typically 8px. Used for search, app links, or settings menus. Border radius is often 12px or 16px to match general softness.

## Guidelines

### Do

- Prioritize Cloud White (#ffffff) for all main page and card backgrounds to ensure a clean, high-contrast canvas.
- Use Techno Pink (#ff37c7) exclusively for primary calls-to-action and active states to maintain visual hierarchy and brand recognition.
- Apply a border-radius of 999999px for all primary and secondary buttons, creating distinct pill shapes.
- Standardize text colors to Ink Black (#131313) for headings and primary content, Dim Gray (#222222) for secondary, and Ash Gray (#6a6a6a) for tertiary details.
- Apply the Basel typeface with a global letter-spacing of -0.02em across all text elements to create a characteristic compact, refined look.
- Maintain 8px as the primary `elementGap` for horizontal and vertical spacing between related UI elements.
- Use a default border-radius of 12px for interactive icons and other contained elements, contrasting with the soft card radius.

### Don't

- Do not introduce new color hues; leverage the existing vibrant accent palette and neutral scale for new features.
- Avoid using hard-edged rectangles for interactive elements; all buttons and most content containers should have a significant border radius (12px, 20px, or 999999px).
- Don't rely on shadows for elevation; instead, use subtle background color changes (e.g., from #ffffff to #f2f2f2) or the blurred background elements for visual depth.
- Do not use highly saturated colorful backgrounds. The backgrounds should remain neutral, allowing the blurred elements and UI accents to provide color.
- Avoid decorative typography; all text should use the Basel typeface in its defined weights and sizes.
- Do not use inconsistent padding for components; adhere to the established spacing scale (e.g., 4px, 8px, 12px, 16px) for interior padding.
- Never use the browser default link color (#0000ee); all links should be Ink Black (#131313) or a semantic color like Success Green (#0c8911) as context dictates.
