Turn one color into a complete, ready-to-use UI palette. Pick a starting color and PaletteDesk generates a role-based palette for your interface - with live UI previews, WCAG contrast checks, SVG patterns, and instant export to CSS, Tailwind, and JSON. Built on OKLCH for perceptually consistent colors, so your palette stays balanced across lightness and chroma. See your colors in context, not just as hex codes. One color - a complete UI system.
