# Design Brief: Vibrant Pop (with Neo-Brutalism)
Full-bleed high-saturation brand backdrops, oversized bold display type, and high-contrast buttons, common across creator tools and consumer apps.
## Design Tokens
```css
:root {
--background: #18ae54;
--surface: #f4f5f6;
--foreground: #052a19;
--muted-foreground: #627169;
--accent: #ff5100;
--radius: 4px;
--font-heading: "Arial", ui-sans-serif, system-ui, sans-serif;
--font-body: "Arial", ui-sans-serif, system-ui, sans-serif;
}
```
Color area ratio: Background #18AE54 (~63%) · Surface #F4F5F6 (~24%) · Text #052A19 (~7%) · Muted Text #627169 (~3%) · Accent #FF5100 (~3%). Background and surface dominate the canvas; reserve the accent color for primary buttons and active states.
## Layout & Conversion Structure
- Hero layout: Split Copy & Visual
- Navigation: Full-Width Top Bar
- Theme & density: Light · Balanced
- Border radius & elevation: Small Radius; use elevation shadows to separate layers
- Primary visual medium: Product UI Screenshot / Component
- Conversion CTA: Download App / Install Extension · Trust bar uses Stacked Avatars & Testimonials
- Headline hook: Category Positioning Anchor
- Hero components: Large Hero Product Shot, Metrics Strip
- Spatial layout notes: Split Copy & Visual hero structure paired with download app / install extension CTA and stacked avatars & testimonials.
- Visual summary: Vibrant Pop (Light canvas, balanced density) featuring split copy & visual layout and product ui screenshot / component visuals.
## Avoid
- Muted corporate gray palettes
- Tiny low-contrast body text
- Overly formal enterprise tables
Implement the UI following the design tokens and layout specifications above: use only these color variables, and reserve the accent color strictly for primary actions and active states. Adopt only this visual style—never copy any reference product’s brand name, logo, copy, or imagery.
