AI-Powered Color Contrast Checker

(finally verify those "unknown" contrast issues)

Traditional scanners flag color contrast issues but can’t verify them when elements use positioning, opacity, gradients, or background images – leaving you with a pile of manual checks. Our AI-powered contrast checker analyzes these complex scenarios and automatically confirms approximately 80% as pass or fail, saving you hours of review time.

Key AI Color Contrast Features

Handles Complex Backgrounds

Our AI analyzes elements over background images, gradients, and layered content that traditional scanners mark as “unable to determine.”

Detects Opacity and Transparency

Calculates effective contrast ratios even when elements use opacity, rgba values, or semi-transparent overlays.

Resolves Positioning Challenges

Accurately evaluates contrast for elements using absolute, relative, or fixed positioning—no more false “needs review” flags.

80% Auto-Resolution Rate

Dramatically reduce manual review time by automatically confirming the vast majority of flagged contrast issues as pass or fail.

Eliminate Manual Review Bottlenecks

Stop spending hours manually checking contrast issues that scanners couldn’t verify. Let AI do the heavy lifting so you can focus on issues that truly need human judgment.

  • Automatically verify contrast on complex visual layouts
  • See clear pass/fail results instead of "unable to determine"
  • Export verified results for client reports and documentation

A variety of color samples are taken around the text to ensure that each letter has sufficient contrast with the background image behind it.
