Purple Ice — Unified Design System

Establishing a multi-brand token architecture, accessible component libraries, and unified design-to-code governance across Student, Teacher, Parent, and Admin portals.

Design Systems Token Engine Multi-Platform WCAG AAA
Purple Ice is CoSchool's unified design system spanning four specialized platforms: Student (light theme), and Teacher, Parent, and Admin (dark themes). It encapsulates core typography, spacing rhythms, color ramps, and reusable component definitions, aligning design and front-end engineering teams for scalable, consistent product rollouts.

Token Foundations & Multi-Theme Architecture

To support diverse user environments — from elementary students using bright interfaces in daylight to school administrators managing data in high-density night shifts — we structured tokens across three layers:

Global Tier (Primitive)

Raw palette scales, font weights, standard radii, and elevation shadows agnostic of brand context.

Semantic Tier (Intent)

Contextual tokens like --color-surface-raised, --color-brand-accent, and --border-subtle.

Component Tier (Scoped)

Component-specific parameters guaranteeing zero visual regression across platform builds.

Accessibility Compliance

Strict contrast checking across light and dark modes achieving WCAG 2.1 AAA contrast ratios.

Interactive Sandbox & Documentation

The Purple Ice design system includes a live, in-browser interactive showcase where engineers and designers can test token states, explore typography scales, preview interactive components, and export live CSS and JSON definitions.
