The hex color #0B51DB, also known as Science Blue, presents several accessibility considerations for web developers. Its relatively low luminance value means it needs careful pairing with text and background colors to ensure sufficient contrast. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal-sized text and 3:1 for large text (14pt bold or 18pt regular) to meet Level AA compliance. When used as a background color, white or very light shades of yellow or green are good choices for text color to provide sufficient contrast. Conversely, if #0B51DB is used for text, a white or similarly light background is crucial. Avoid pairing it with dark shades or colors close to it in the color spectrum, as this can make text illegible for users, especially those with visual impairments. Testing with accessibility tools and getting feedback from users are essential to ensure optimal readability and usability.
