Step 2: Replace :root and .dark sections

Find existing :root and .dark blocks in globals.css and replace with chosen theme variables.

Step 3: Verify Tailwind Config

Ensure tailwind.config.ts references CSS variables:

typescript
theme: {
  extend: {
    colors: {
      background: 'hsl(var(--background))',
      foreground: 'hsl(var(--foreground))',
      // ... other color mappings
    }
  }
}

CSS Variable Structure

Each theme includes:

Light Mode (:root):

  • --background: Page background
  • --foreground: Main text color
  • --primary: Primary action color (buttons, links)
  • --secondary: Secondary elements
  • --accent: Highlights, badges
  • --muted: Disabled states, subtle backgrounds
  • --destructive: Error/delete actions
  • --border, --input, --ring: UI element styling
  • --card, --popover: Elevated surfaces
  • --chart-1 through --chart-5: Data visualization colors
  • --sidebar-*: Sidebar-specific colors
  • --radius: Border radius (e.g., 1.25rem)
  • --shadow-*: Box shadow definitions
  • Font variables: --font-sans, --font-serif, --font-mono

Dark Mode (.dark): Same variable names with adjusted values for dark backgrounds.

Example: Applying Claude Theme

User request: "Change to Claude theme"

Action:

  1. Read current app/globals.css
  2. Replace :root section with Claude light mode variables
  3. Replace .dark section with Claude dark mode variables
  4. Preserve other CSS (typography, base styles)

Claude Theme CSS Variables:

Getting Full Theme CSS

To get complete CSS for any theme:

  1. Official Themes Source: https://ui.shadcn.com/themes
  2. Community Themes:
    • tweakcn themes: Search "tweakcn shadcn themes"
    • styleglide themes: Search "styleglide shadcn themes"
  3. Theme Generators: Online tools for creating custom themes

Workflow:

  • User requests theme → Look up theme CSS variables
  • If theme not in this skill → Search official sources
  • Copy :root and .dark blocks → Replace in globals.css

Color Space: OKLCH

Themes use OKLCH color space:

  • Format: oklch(lightness chroma hue)
  • Benefits: Perceptually uniform, better gradients, wider gamut
  • Browser Support: Modern browsers (2023+)
  • Fallback: Consider HSL fallbacks for older browsers if needed

Theme Selection Guide

Corporate/Professional: Default, Blue, Cleanslate, Modern Minimal Creative/Bold: Cyberpunk, Neo Brutalism, Claude, Claymorphism Nature/Organic: Citrus, Kodama Grove, Spring Bouquet Warm/Inviting: Amber Minimal, Sunset Horizon, Red Developer/Tech: Supabase, Vercel, Typewriter Minimal/Clean: Modern Minimal, Vercel, Typewriter, Cleanslate

Usage Tips

  • Test both modes: Always verify light + dark mode appearance
  • Accessibility: Check contrast ratios (WCAG AA minimum)
  • Brand alignment: Match theme to brand colors/identity
  • User preference: Support system theme detection
  • Gradual changes: Preview theme before committing
  • Custom tweaks: Adjust individual variables post-application

Common Requests

"Change to dark theme" → Apply dark mode toggle, not full theme change "Make it more colorful" → Suggest Cyberpunk, Neo Brutalism, Spring Bouquet "Corporate look" → Default, Blue, Cleanslate "Match Supabase" → Apply Supabase theme "Minimalist design" → Modern Minimal, Vercel, Typewriter
