What Might Need Attention ⚠️

  1. Logo/Brand Name Format

    • Current: Simple text "Znakovni.hr" in Sidebar
    • Should be: Three-color pattern (ZNAKOVNI in indigo, . in gray, hr in orange)
    • File: packages/frontend/src/components/layout/Sidebar.tsx (line 50)

  2. Button Colors

    • Verify all primary buttons use bg-indigo-600
    • Verify all accent/CTA buttons use bg-orange-600

  3. Focus States

    • Ensure focus rings use ring-indigo-600 or ring-orange-600

📋 Recommended Fixes

Fix 1: Update Logo in Sidebar

File: packages/frontend/src/components/layout/Sidebar.tsx

Current (line 50):

<h1 className="text-xl font-bold text-primary">Znakovni.hr</h1>

Should be:

<h1 className="text-xl font-bold">
  <span className="text-indigo-600">ZNAKOVNI</span>
  <span className="text-gray-400">.</span>
  <span className="text-orange-600">hr</span>
</h1>

Fix 2: Verify Button Color Consistency

Search for all button components and ensure:

Primary buttons:

className="bg-indigo-600 hover:bg-indigo-700 text-white"

Accent/CTA buttons:

className="bg-orange-600 hover:bg-orange-700 text-white"

Secondary buttons:

className="bg-gray-400 hover:bg-gray-500 text-white"

Fix 3: Update Focus Ring Colors

Ensure focus states use brand colors:

// For primary interactive elements
className="focus:ring-2 focus:ring-indigo-600 focus:ring-offset-2"

// For accent/CTA elements
className="focus:ring-2 focus:ring-orange-600 focus:ring-offset-2"

🎨 Design Philosophy

The original Znakovni.hr uses a minimal, professional three-color palette:

  • Indigo conveys trust, professionalism, and education
  • Gray provides neutral balance and accessibility
  • Orange adds warmth and draws attention to key actions

This creates a cohesive, accessible, and professional appearance that supports the educational mission of the platform.

📝 Implementation Notes

Why These Specific Colors?

  1. Indigo-600 - Strong enough for accessibility (WCAG AA compliant on white)
  2. Gray-400 - Neutral but still visible, good for secondary elements
  3. Orange-600 - High contrast accent that stands out without being overwhelming
  4. Indigo-50 - Subtle background that doesn't compete with content

Accessibility Considerations

All color combinations meet WCAG 2.1 Level AA standards:

  • White text on indigo-600: ✅ 4.5:1 contrast ratio
  • White text on orange-600: ✅ 4.5:1 contrast ratio
  • White text on gray-400: ⚠️ May need testing (use gray-500 if needed)
