The color #1518D1, a dark blue hue, presents some accessibility challenges, particularly concerning color contrast. When used as text, it requires a light background to meet WCAG (Web Content Accessibility Guidelines) standards for sufficient contrast. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text (14 points bold or 18 points regular). Using this dark blue on darker backgrounds can make text illegible for users with low vision or color blindness. In interactive elements like buttons, sufficient contrast is crucial for users to perceive the interactive affordance. Ensure that the color combinations provide enough visual distinction between elements. Additionally, avoid relying solely on color to convey information; supplement with text labels or icons to accommodate users with color vision deficiencies. Thorough testing with accessibility tools and user feedback is essential to ensure inclusive design.
