WCAG Color Contrast Checker

A link may look distinguishable, but low contrast can make it hard to see, especially for users with visual impairments. Always verify contrast against both the background and surrounding text. Links must have a minimum contrast ratio of 4.5:1 against the background. If links rely only on color for differentiation, they must also have at least 3:1 contrast against surrounding text to remain readable.

Bold formatting enhances readability but does not replace contrast requirements. Even bold links need at least 3:1 contrast against surrounding text to ensure accessibility. If contrast is too low, consider adding underline or color adjustments to make the link more distinguishable.

Underlines improve visibility, but if links rely only on color, they require a 4.5:1 contrast ratio against surrounding text. Otherwise, they may blend in and become hard to spot. To avoid confusion, ensure links are either visually distinct by color and contrast or consistently underlined.

Hover states should not be subtle design elements that reduce visibility. Low-contrast hover effects can make links harder to recognize, especially for users with color blindness. Ensure that hover states maintain strong contrast, and avoid color changes that lower visibility when interacted with.

Designs that look good in bright environments can struggle in dimly lit settings. Ensure your text remains legible in various lighting conditions to avoid frustration for users in low-light environments.
