Free Color & Design Tools
Free color tools for designers and front-end developers. Convert a HEX code to RGB and HSL (and back), and check whether two colors meet WCAG accessibility contrast ratios for AA and AAA. Each tool shows a live swatch and the exact values you can paste straight into CSS, and explains the conversion or the contrast formula it uses. Everything runs in your browser — no sign-up, no uploads.
A Color Contrast Checker ensures your text is readable against its background by calculating the WCAG 2.x contrast ratio and verifying compliance with accessibility standards. Perfect for web designers and developers building inclusive interfaces.
