Color Tool

The tool analyzes color values to help create accessible UI color systems. It supports hex, RGB, and HSL inputs, and can generate contrast ratings against a chosen background. It computes WCAG-compliant contrast ratios, flags AA/AAA eligibility, and suggests alternative colors for improved readability. Users can also generate coherent palettes using theory-based modes (analogous, complementary, triadic) and preview how colors interact under different lighting. This combined capability helps designers, developers, and brand teams ensure legible typography, usable controls, and consistent branding across platforms. The core value lies in accelerating color decisions with objective analytics and theory-driven palettes, reducing guesswork in accessibility audits and onboarding new teammates. Core features include input validation, contrast calculations, palette generation, and export options for CSS variables or JSON. Real-world use cases include auditing existing websites for accessibility compliance, starting new product interfaces with accessible defaults, and producing brand-safe palettes for marketing materials. By combining rigorous color science with practical palette planning, the tool enables faster iterations and more reliable accessibility outcomes.
