Color Tools

• Color Converter

  Convert a color from hex, rgb(), hsl(), or a common CSS color name to every common format. Space-separated rgb()/hsl() and hex without # are accepted. See a live preview swatch on the Convert tab.

• Contrast Checker

  Enter foreground color in Input and background color in Tool Settings. Reports pass/fail for normal and large text at AA and AAA thresholds — ratio calculator for debugging, not a compliance certification. Semi-transparent foreground colors are composited on the background before calculating contrast.
