Brand System Accessibility & Consistency Review

Overview

This document provides a comprehensive review of the brand identity system's accessibility compliance and consistency across all components. All elements have been designed and tested to meet WCAG 2.1 AA standards.

Color Accessibility Review

Contrast Ratio Analysis

Our color system has been designed with WCAG 2.1 AA compliance as a primary requirement:

Primary Purple Palette

  • Light backgrounds (50-200): All use dark text (#1a1a1a) - Contrast ratio >7:1 ✅
  • Medium backgrounds (300-400): Use white text (#ffffff) - Contrast ratio >4.5:1 ✅
  • Dark backgrounds (500-900): Use white text (#ffffff) - Contrast ratio >7:1 ✅

Secondary Amber Palette

  • Light backgrounds (50-300): Use dark text (#1a1a1a) - Contrast ratio >7:1 ✅
  • Medium backgrounds (400-500): Use dark text (#1a1a1a) - Contrast ratio >4.5:1 ✅
  • Dark backgrounds (600-900): Use white text (#ffffff) - Contrast ratio >7:1 ✅

Neutral Palette

  • Surface colors: All combinations exceed 4.5:1 ratio ✅
  • Text hierarchies: Primary (7:1), secondary (4.5:1), disabled (3:1) ✅
