Palette & Contrast

Extract approximate colors from your own image, copy HEX and RGB values and check accessible contrast.

Approximate colors sampled locally. Maximum 12 MB and 16 million pixels.

Readable worlds begin with readable words.

    How to use this tool

    Choose your own still image to extract up to six approximate colors, then copy a HEX or RGB value. Set foreground and background colors below to check their contrast. Selecting a palette swatch uses it as the foreground color.

    Example and method

    WCAG AA requires at least 4.5:1 for normal text and 3:1 for large text. Large text means at least 18pt regular or 14pt bold. Essential non-text interface components generally need 3:1 against adjacent colors.

    Limits and privacy

    This checker compares two opaque sRGB colors. It does not evaluate gradients, transparency, font rendering, every adjacent UI color, focus behavior or overall accessibility. The image palette is sampled and approximate. Image limits are 12 MB and 16 million pixels.
