Color tools

Convert formats (including OKLCH), explore HSL-based harmonic relatives, check text contrast against WCAG thresholds, or pick from the classic 6×6×6 web-safe set—all in your tab.

Common use cases

  • Use the converter when you need the same color in HEX, rgb(), hsl(), or OKLCH for different parts of a stack.
  • Open the WCAG contrast checker when text must meet accessibility ratios on a solid background.
  • Browse web-safe swatches when you want a small, classic palette or to match older HTML constraints.

Common mistakes to avoid

  • Treating hub tools as interchangeable

    Conversion tells you equivalent syntax; contrast checking answers a different question (readability). Run both when both matter.
