The converter accepts color values recognised by your browser, including common HEX, RGB, RGBA, HSL, HSLA, and named-color inputs. It displays HEX, RGB, HSL, and approximate CMYK results. Support for newer CSS color formats may vary by browser.
The tool calculates the contrast ratio between foreground and background colors and compares it with common WCAG AA and AAA thresholds. This result covers color contrast only and is not a complete accessibility audit.
Color conversion and analysis happen locally in your browser. This tool does not upload or store the color values you enter on ToolCookie servers.
You can export a generated palette as a CSS file. The tool does not automatically save palettes in your browser for future visits.
