Paste in a brand hex and get back a complete 11-shade color system with Tailwind v4 CSS ready to copy into your project. It generates the full 50-950 scale using HSL manipulation to keep hue consistent while varying lightness, maps semantic tokens like primary, muted, and accent for both light and dark modes, and runs WCAG contrast checks so you know if your text combinations actually pass AA or AAA. The dark mode implementation follows proper inversion patterns, swapping extremes while keeping the brand color recognizable. Useful when you're spinning up a new project and need a real design system from a single color, not just random shades eyeballed in Figma.
