Why this matters
Readable text builds trust — low contrast frustrates users and hurts conversion.
WCAG contrast helps people with low vision, color deficiency, and bright-screen glare.
Many accessibility complaints and legal risks start with color pairs that fail basic contrast checks.
Checking contrast during design is faster and cheaper than fixing issues after launch.
