Test your palette on real components
Before integrating a palette into your project, visualize it on real UI components. Our tool displays your colors on buttons, cards, forms and other interface elements to ensure the final result matches your expectations. Preview your palette applied to real UI components: buttons, cards, forms, badges, alerts — to validate the look before Figma or code integration. Instantly convert between HEX, RGB, HSL, HSV and CMYK, adjust hue, saturation and lightness with real-time preview and check WCAG AA/AAA contrast for sRGB-compliant accessibility.
Interactive components
Buttons display their hover, active and disabled states. Forms show focus and validation. Cards present shadows and borders. A complete and realistic preview.
Light and dark mode side by side
Instantly visualize your palette in light and dark mode. Check that contrasts are sufficient in both modes and that the atmosphere remains coherent. Adjust colors if necessary before integration.
Integrated accessibility validation
Each text/background combination is analyzed according to WCAG standards. Visual indicators signal contrast issues. Fix accessibility errors before they reach your production.
Semantic palette for design systems
Define semantic roles for your colors: primary, secondary, destructive, success, warning, info. Our tool automatically applies these colors to appropriate components according to UI conventions.
Export for modern frameworks
Export your validated palette as CSS variables, Tailwind config or shadcn/ui format. The code is ready to use for React, Vue, Angular or any modern web project. Integration in seconds.
