Design Systems — Styles, Tokens & Libraries
The Single Source of Truth
Color styles, text styles, effect styles, shared libraries, and how to build a consistent design system.
Design System Pieces
Styles & Libraries
🎨
Color Styles
Named, reusable colors (e.g. "Primary/500") applied consistently across every screen.
🔤
Text Styles
Saved font, size, weight, and line-height combinations for headings and body text.
✨
Effect Styles
Reusable shadows, blurs, and other visual effects.
📚
Shared Libraries
A published file of styles/components other Figma files can subscribe to and reuse.
✅
Why design systems scale teams
When a color style changes once in the shared library, every screen using it updates automatically — instead of a designer manually finding and fixing every instance.
