The hex color #280bdb presents some accessibility challenges, particularly when used as a foreground color on a white or light background. Its luminance is relatively low, meaning the contrast ratio might not meet WCAG (Web Content Accessibility Guidelines) standards for normal text. For optimal readability, especially for users with visual impairments, it's crucial to pair this dark blue with a very light color, such as white or a pale yellow, to ensure sufficient contrast. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Tools like contrast checkers can help verify compliance. Using #280bdb for decorative elements or as a background color for light text can be more acceptable, but careful consideration is always necessary to prioritize accessibility and ensure a positive user experience for everyone.
