# 🎨 Design Brief: Accessibility Extension of Brand Guidelines ## Project Objective Expand the existing brand guidelines to support **accessible color-blind–friendly modes** alongside existing **light/dark themes**. The system should preserve the **core brand feel** — a metallic, shade-contrast–driven aesthetic with a dynamic ring logo — while ensuring legibility and usability for users with different forms of color blindness. The final deliverable should be an **extended brand guideline document** and a **Tailwind implementation direction** that defines scalable, maintainable design tokens for multiple vision modes. --- ## Brand Context * **Primary Identity**: Metallic ring logo, dynamically adapting between light and dark modes. * **Style**: Minimalist, shade/contrast-based rather than hue-driven. Five primary color-ways, designed as **high/low contrast pairs** within a limited hue space. * **Current UX**: Light/Dark toggle with Tailwind extension support. --- ## Accessibility Scope The design system must extend to support users with the following visual deficiencies: * **Protanopia** (red-blind) * **Deuteranopia** (green-blind) * **Tritanopia** (blue-blind) * **Achromatopsia** (complete color blindness) Goals: * Maintain brand recognizability and aesthetic. * Prioritize **contrast, brightness, and texture cues** over exact hue fidelity. * Use **redundant cues** (shapes, icons, labels) for critical distinctions, not just color. * Ensure **WCAG AA or better** contrast ratios across all themes. --- ## UX/UI Guidelines * **Light/Dark toggle** remains the primary visible control in the header. * **Accessibility themes** (vision deficiency modes) are discoverable in a **preferences/settings panel**, not exposed as clutter in the main UI. * Maintain **consistent interactions, spacing, and typography** across all modes. * Accent hues should shift per mode as needed to preserve differentiation (e.g., avoid red/green conflicts for Deuteranopia, adjust blue/yellow for Tritanopia). --- ## Tailwind Implementation Direction * **Approach**: Implement all palettes via **CSS variables** mapped to Tailwind design tokens. * **Structure**: * Define 5 base shade palettes (`brand-1` → `brand-5`). * Define **semantic tokens** (`--color-bg`, `--color-fg`, `--color-accent`, `--color-ring`) applied via `[data-theme="..."]`. * Extend Tailwind config to map these tokens into utility classes. * **Theme Switching**: * Use `data-theme` attributes (`light`, `dark`, `protanopia`, `deuteranopia`, `tritanopia`, `achromatopsia`). * JS toggles simply change the attribute on `` or ``. * **Testing**: Validate palettes in Chrome DevTools “Emulate vision deficiencies” and ensure minimum contrast ratios. --- ## Deliverables 1. **Updated Brand Guidelines** * Extended color system with accessible variants. * Documentation on maintaining brand feel across modes. * Guidance on redundant visual cues. 2. **Tailwind Implementation Guide** * Config example with tokens. * Example `data-theme` usage and switching mechanism. * Sample component styles demonstrating accessible variants. --- ⚡ **Key Success Metric**: The metallic brand identity remains intact and aesthetically pleasing while **8%+ of male users with color blindness** experience equal legibility, usability, and emotional resonance with the brand. ---
