Insufficient Color Contrast
What the scanner found
The most widespread issue by far. Low-contrast text appeared on 86 of 100 homepages, most often in navigation links, promotional badges, secondary CTAs, and footer copy. The average affected page had 3.6 distinct contrast failures.
E-commerce context
Price labels, 'Sale' badges, and ghost-style buttons were the most common offenders. Many stores use light-grey text on white for secondary information, which fails the 4.5:1 ratio requirement.
