What Blyxo Tests
Pixel-perfect contrast analysis across all WCAG color and visual criteria
WCAG AA Contrast Checking
Automated detection of text failing 4.5:1 ratio for normal text and 3:1 for large text (18pt+ or 14pt+ bold).
WCAG AAA Enhanced Contrast
Stricter 7:1 contrast checking for normal text and 4.5:1 for large text to meet Level AAA requirements.
Non-text Contrast
Validate UI components (buttons, form inputs, focus indicators) and meaningful graphics meet the 3:1 ratio requirement (WCAG 1.4.11).
Color-Only Link Detection
Detect links within body text that rely on color alone — no underline, bold, or icon — which fails WCAG 1.4.1 Use of Color.
Error State Color Analysis
Flag form validation errors relying solely on red color without accompanying text, icons, or patterns.
Text Resize Support
Test pages at 200% zoom to verify content reflows without loss of functionality (WCAG 1.4.4).
Images of Text Detection
Identify large images inside heading elements that may be text rendered as images (WCAG 1.4.5).
