HexPalette is a color intelligence platform for exploring colors in depth and turning them into full UI color systems, not merely looking up a single hex code.
It goes beyond a lookup tool with WCAG contrast testing, nearest-color matching, and theme generation that outputs WCAG-safe, OKLCH-based systems ready to export to CSS, Tailwind, or design tokens.
Design system teams wanting a single color to grow into a full, accessible UI theme, rather than manually building out shades and checking contrast separately.
The old ww1.hexpalette.com subdomain no longer resolves. Use hexpalette.com directly if an older bookmark or link stops working.
A free tool to help you find the right colour combinations for your next project.
