Pick a color and convert between HEX, RGB, and HSL with a built-in WCAG contrast checker.
Use the color swatch or type into any field to pick a color; all formats stay in sync. Preview swatches show your color on light and dark backgrounds. The WCAG section computes the contrast ratio between foreground and background and flags AA/AAA pass for normal and large text. The palette shows five analogous colors shifted by fifteen and thirty hue degrees in both directions.
