Color

Pick, name, convert and check colors.

Color tools take the guesswork out of working with color on the web and in design. Convert a HEX code to RGB or HSL, pick a shade visually and copy its exact value, find the name of a color, or check that two colors have enough contrast to stay readable and accessible. They are built for front-end developers translating a design into CSS, designers building a palette, and anyone making sure text passes WCAG contrast requirements. Every conversion happens instantly in your browser with no uploads and no sign-up. Use the HEX to RGB converter to drop values straight into your stylesheet, a color picker to grab the perfect shade, or a contrast checker to confirm your UI is legible for everyone. Free, fast, and made to give you a copy-ready answer in seconds.
