Design Systems tips
The lightness scale at the bottom generates shades from 10% to 90% — great for building a token-based palette like Tailwind's 50–900 scale.
Start with your brand colour, convert to HSL, then create a scale by keeping H and S fixed while varying L from 10% to 90%.
Export all shades as HEX for Figma, as RGB for code, and as HSL for your CSS custom properties system.
Ensure sufficient contrast between text and background colours. Use the WCAG 4.5:1 contrast ratio guideline for body text readability.
