SETI Brand Styling
Overview
Applies SETI's space-themed design system to any artifact that requires the official SETI look-and-feel. The design system features deep space black backgrounds with stellar silver metallic primary accents and ice cyan secondary accents for a sophisticated, modern sci-fi aesthetic.

Design Philosophy
- Deep Space Black: Pure dark backgrounds that evoke the infinite vastness of space
- Metallic Sophistication: Silver and steel tones for a refined, high-tech aesthetic
- Cool Minimalism: Ice cyan accents used sparingly for futuristic highlights
- No Blue-Purple or Orange: Avoids clichéd sci-fi colors in favor of distinctive silver metallic and ice cyan
- High Contrast: Ensures readability with carefully balanced foreground/background relationships
- Modern & Clean: Sleek layouts with purposeful use of space and metallic textures
Theme System
SETI supports two accent color themes, both using the same deep space black base:
Theme 1: Stellar Silver (星际银色) - Default
Metallic, sophisticated - inspired by spacecraft hulls and advanced technology.
- Accent Color: #9ca3af (Silver 400)
- Character: Sophisticated, metallic, professional
- Use for: Links, decorative borders, hover states, metallic glows
Theme 2: Ice Cyan (冰晶青色)
Cool, futuristic - inspired by cryogenic systems and deep space ice.
- Accent Color: #67e8f9 (Ice 300)
- Character: Cool, futuristic, ethereal
- Use for: Links, decorative borders, hover states, subtle glows
IMPORTANT: Accent Color Usage Rules
DO use accent colors for:
- Links and interactive elements
- Decorative borders and dividers
- Background glows and gradients (subtle)
- Hover/focus states
- Icons when they need emphasis
- Selection highlights
DO NOT use accent colors for:
- Main headings/titles (use space-50 or space-100)
- Body text (use space-200 or space-300)
- Large text blocks
- Backgrounds (except subtle glows)

Best Practices
- Dark Mode First: Design primarily for dark mode
- Theme Consistency: Use CSS variables for theme-aware colors
- Metallic Restraint: Use metallic effects sparingly for emphasis
- Accent Sparingly: Use primary/accent colors only for emphasis
- Hierarchy: Use color, size, and spacing to establish visual hierarchy
- Consistency: Stick to the defined color palette, avoid custom colors
- Testing: Test in both themes (Stellar Silver and Ice Cyan)
Technical Details
Theme Switching
Theme switching is handled via:
- CSS classes on
<html>:dark theme-silverordark theme-ice -
data-themeattribute for JavaScript access - ThemeContext React context for components
- localStorage persistence with key
seti-color-theme
Tailwind Configuration
The design system is implemented through Tailwind CSS configuration:
- Custom color definitions in
tailwind.config.ts - Dark mode support with
darkMode: 'class' - Extended theme with custom animations and utilities
- Theme-specific colors (silver, ice) alongside CSS variable-based primary
CSS Variables
CSS custom properties for theming:
-
--background,--foreground -
--primary,--primary-foreground -
--primary-50through--primary-950(full scale) -
--accent,--accent-foreground -
--muted,--muted-foreground -
--border,--input,--ring
Component Integration
When adding new components:
- Use CSS variable colors (e.g.,
text-primary,bg-primary/10) - Use theme-specific classes when needed (e.g.,
text-silver-300,text-ice-300) - Consider metallic effects for interactive elements
- Maintain accessibility with proper contrast ratios
- Test in both Stellar Silver and Ice Cyan themes
