2026-04-206 min readBy Aqib Nazir
Building an enterprise design system requires consistent color palettes, typography scales, and spacing tokens that adapt seamlessly across light and dark modes.
Defining Semantic HSL Variables
Using HSL coordinates paired with CSS custom variables allows dynamic contrast adjustments across theme modes:
1
Define primary, background, and surface variables in HSL format.
2
Override values inside class boundaries for theme switches.
3
Register variables in your utility CSS theme configuration.
Key Benefits
High Contrast Accessibility: Effortlessly satisfy WCAG AA ratio standards across themes.
Instant Light/Dark Toggling: Zero flash of unstyled content (FOUC).
