Given a primary color, generate a full palette:
// HSL-based palette generation function generatePalette(hue, saturation = 70) { return { 50: `hsl(${hue}, ${saturation}%, 97%)`, 100: `hsl(${hue}, ${saturation}%, 94%)`, 200: `hsl(${hue}, ${saturation}%, 86%)`, 300: `hsl(${hue}, ${saturation}%, 74%)`, 400: `hsl(${hue}, ${saturation}%, 62%)`, 500: `hsl(${hue}, ${saturation}%, 50%)`, // Primary 600: `hsl(${hue}, ${saturation}%, 42%)`, 700: `hsl(${hue}, ${saturation}%, 34%)`, 800: `hsl(${hue}, ${saturation}%, 26%)`, 900: `hsl(${hue}, ${saturation}%, 18%)`, 950: `hsl(${hue}, ${saturation}%, 10%)`, }; }
