The color #2101B3, a dark blue hue, presents accessibility challenges, particularly for users with visual impairments. Its low luminance value (approximately 3%) results in poor contrast against white text, failing WCAG (Web Content Accessibility Guidelines) standards for normal text (AA) and large text (AA). To ensure inclusivity, using #2101B3 requires careful consideration of contrast ratios. Light text on this background is almost unreadable. A lighter background color, such as a light grey or light blue, would significantly improve readability and meet accessibility requirements. Moreover, providing alternative text descriptions for images or elements using this color is crucial. Assistive technologies rely on these descriptions to convey information to users who cannot perceive the color visually. Developers should avoid using this color for essential interactive elements like buttons or links without also providing clear text labels or icons.
