Its relatively low lightness value means it may not provide sufficient contrast against white backgrounds, potentially making text or interactive elements difficult for users with visual impairments to discern. According to WCAG guidelines, sufficient contrast is crucial for readability. When using this color for text, a light-colored background should be avoided. Instead, consider pairing it with very light yellows, oranges, or greens to provide adequate contrast. Ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. For graphical elements and user interface components, a contrast ratio of 3:1 is required. Tools like contrast checkers can assist in verifying compliance with these guidelines, ensuring your designs are accessible to a broader audience, including those with low vision or color blindness. When #174E81 is used for interactive elements, provide additional visual cues, such as underlines or icons, to ensure usability for all users.
