Accessible Palette helps designers create color systems with consistent perceived lightness and WCAG-compliant contrast ratios using advanced color models. Unlike traditional HSL color models, it uses human-vision-aligned models like CIELAB and LCh, ensuring colors with the same lightness have consistent contrast and appearance. This approach simplifies creating accessible color palettes that work well across designs and improve readability and usability for users with visual impairments. The tool leverages chroma.js for generating color ranges and provides resources on accessible color theory for designers aiming to create inclusive digital experiences.
