Implementation Guide

The CHORUS typography system uses a proportional scale with 18px base font size, ensuring consistent scaling across all elements and devices.

Implementation Steps

Configure your build system to use the proportional typography scale with 18px base:

1. Set Root Font Size (CSS)
/* Set 18px as the root font size for complete system scaling */
  html {
  font-size: 18px; /* Base size: 18px instead of browser default 16px */
  }
2. Configure Tailwind Typography (JavaScript)
// tailwind.config.js - Proportional Typography Override
  module.exports = {
  theme: {
  extend: {
    fontSize: {
      'xs': ['0.64rem', { lineHeight: '0.9rem', fontWeight: '400' }],    // 11.52px @ 18px base
      'sm': ['0.8rem', { lineHeight: '1.125rem', fontWeight: '400' }],   // 14.4px @ 18px base
      'base': ['1rem', { lineHeight: '1.5rem', fontWeight: '400' }],     // 18px @ 18px base
      'lg': ['1.25rem', { lineHeight: '1.75rem', fontWeight: '400' }],   // 22.5px @ 18px base
      'xl': ['1.563rem', { lineHeight: '2.125rem', fontWeight: '400' }], // 28.1px @ 18px base
      '2xl': ['1.953rem', { lineHeight: '2.375rem', fontWeight: '400' }], // 35.2px @ 18px base
      '3xl': ['2.441rem', { lineHeight: '2.75rem', fontWeight: '400' }],  // 43.9px @ 18px base
      '4xl': ['3.052rem', { lineHeight: '3.25rem', fontWeight: '400' }],  // 55.0px @ 18px base
      '5xl': ['3.815rem', { lineHeight: '4rem', fontWeight: '400' }],     // 68.7px @ 18px base
      '6xl': ['4.768rem', { lineHeight: '4.75rem', fontWeight: '400' }],  // 85.8px @ 18px base
    }
  }
  }
  }
3. Usage Examples (HTML)

  <h1 class="text-4xl font-bold">Main Heading (55px)</h1>
  <h2 class="text-2xl font-semibold">Section Heading (35.2px)</h2>
  <p class="text-base">Body text (18px)</p>
  <small class="text-sm text-gray-600">Caption text (14.4px)</small>

  <!-- Spacing also scales proportionally with rem units -->
  <div class="p-4 mb-6">Padding and margins scale with base font</div>
Benefit: Changing the root font-size automatically scales all typography and rem-based spacing throughout your application, ensuring consistent proportional relationships across all screen sizes and user preferences.

Our metallic palette works exceptionally well for deuteranopia - carbon, nickel, and mulberry maintain distinct contrast.

Carbon

Excellent contrast, appears as expected

Mulberry

Maintains dark richness, slight blue shift

Nickel

Perfect metallic appearance maintained

Ocean

Appears more blue-gray, excellent contrast

Protanopia (Red-Blind) - 20% of Color Blind Users

Our strategic use of brightness differences ensures full accessibility for protanopia users.

Carbon

Perfect contrast, no color dependency

Coral

Appears dark brown, maintains warning context

Eucalyptus

Appears yellow-brown, retains positive association

Sand

Enhanced yellow appearance, excellent for warnings

Tritanopia (Blue-Blind) - 5% of Color Blind Users

Our earth-tone palette performs excellently for tritanopia, with warm tones remaining distinct.

Walnut

Enhanced warmth, excellent contrast

Ocean

Appears green-gray, maintains cool contrast

Sand

Bright, warm appearance maintained

Mulberry

Appears more red, luxury feel preserved

Accessibility Features

Built-in Support

Motion Design System

Motion Philosophy

The CHORUS motion system embodies the continuous flow of the Möbius ring, creating sophisticated orchestration through purposeful, elegant animations. Every movement serves a functional purpose while maintaining the ultra-minimalist aesthetic.

Seamless Flow

Like the Möbius ring, animations flow naturally without jarring interruptions

Purposeful Motion

Every animation guides attention and enhances understanding

Performance First

Optimized animations that respect user preferences and device capabilities

Animation Principles

Easing & Timing

Sophisticated easing creates natural, comfortable motion that feels organic and polished.

Primary Easing
cubic-bezier(0.4, 0.0, 0.2, 1)

Standard Material Design easing for most interactions

Chorus Signature
cubic-bezier(0.25, 0.46, 0.45, 0.94)

Custom easing for signature CHORUS animations

Duration Guidelines

150ms
Micro Interactions
Hover states, button press
300ms
UI Transitions
Modal open, drawer slide
500ms
Page Transitions
Route changes, complex layouts
800ms
Attention & Delight
Logo reveal, success states

Accessibility & Performance

  • Reduced Motion: Respect prefers-reduced-motion user preferences
  • Performance Budget: Limit concurrent animations to maintain 60fps
  • Progressive Enhancement: Ensure functionality without animation
  • Focus Management: Preserve focus during animated transitions
  • Content Priority: Never let animation delay critical content

Warning Icon

Do not generate imagery of humans, be it a likeness or representation of a living person or not.

This cheapens the brand and goes against the CHORUS ethos of utilising human talents.

We already use AI to its best abilities to generate our customers products and our own, assigning human likeness is misguided.

Generated imagery of systems or diagrams is an acceptable use provided results are checked

Use AI to the best of its talents and sometimes that means creating imagery beyond human capability or budgets.
