DAC Color Contrast Checker
by Kenneth Akomea
Description
DAC Colour Contrast Checker
Check colour contrast the way you work: from photos, your gallery, or any webpage. See instantly whether text and background combinations meet WCAG 2.2 and get clear, actionable feedback.
What you can do:
On photos from the camera or your gallery, tap "Analyse Contrast" and the app scans the image for text regions, measures each area's colour contrast, and marks where it fails WCAG AA or AAA.
Issues appear as overlays on the image and in a dedicated Issues list; tap any finding to load those colours and fix them. You can also capture a scene with the camera or pick an image from your gallery and use the pipette to sample any colour.
For the web, open any URL and sample colours directly from the page—handy for checking existing sites or matching a brand.
Contrast ratio and WCAG 2.2 ratings (Normal and Large text, AA and AAA) update in real time. Switch between a quick Check view and a detailed Compliance view; when you've run analysis on an image, an Issues tab shows what was detected and where. If a pair doesn't pass, the app suggests better foreground/background options—tap one to apply it and recheck. Use the sample text area with your chosen colours and adjust font size, weight, and style so the preview matches how you'll use them. Save colour pairs with an optional name and revisit them from Colour History; tap a saved pair to load it back. Share your analysis or copy hex and RGB values in one tap.
Who it's for:
Designers, developers, content creators, and anyone who cares about readable, accessible colour choices. Built with input from the Digital Accessibility Centre and aligned to WCAG 2.2, so you can trust the results whether you're designing a site, app, or document.
Privacy:
All analysis runs on your device. We don't collect, store, or send your data. Colour history stays only on your iPhone or iPad.
