FAQ

Questions Color Difference Engine owners ask.

  • 01

    What color models are supported?

    The engine supports CIE76, CIEDE2000, and OKLAB for calculating perceptual distance.

  • 02

    How do I use the ranking capability?

    Use rank_colors_by_similarity by providing a target Hex color and an array of candidate Hex strings.

  • 03

    Can I check if two colors are within a specific tolerance?

    Yes, the evaluate_proximity capability allows you to define a threshold value to see if the difference is small enough.
