FAQ

Questions Color Accessibility Engine owners ask.

  • 01

    How does this engine ensure color palettes look good?

    The engine uses the LCH (Lightness, Chroma, Hue) color space instead of HSL. This ensures that when you shift hues, the perceived lightness and saturation remain constant, avoiding muddy colors.

  • 02

    Can I check if my brand color is accessible?

    Yes. By using calculate_accessibility, you can check if your base HEX color meets WCAG 2.1 AA or AAA standards for both normal and large text against pure black and white.

  • 03

    What is Delta-E?

    Delta-E is a metric used to quantify the difference between two colors. This engine uses the CIEDE2000 formula to provide a value that matches how humans actually perceive color differences.
