Generate accessible color palettes by computing perceptually uniform color ramps using the OKLCh color space. This ensures consistent lightness and chroma across all steps while automatically validating contrast ratios against WCAG 2.2 standards for both light and dark modes.

The best way to implement a three-layer design token system for dark mode is to structure tokens into primitive, semantic, and component layers. This semantic mapping enables effortless theme switching and visual coherence across UI design systems.

OKLCh color space improves UI design system accessibility by providing perceptually uniform color generation. It computes palettes with consistent lightness and chroma, allowing systematic tokenization that satisfies both WCAG 2.x contrast and non-text contrast criteria.

Yes, you can audit current CSS theme tokens for both text and non-text contrast compliance. The system automatically validates contrast ratios against WCAG 2.2 standards and APCA guidelines, ensuring web interfaces meet accessibility requirements in light and dark modes.

Computed design tokens often fail WCAG contrast checks in dark mode due to non-uniform lightness perception in standard color spaces. Using OKLCh ensures perceptually uniform color ramps, systematically fixing contrast ratio failures across both light and dark themes.
