The color #101288, also known as Ultramarine, presents unique accessibility considerations for web developers. Its dark hue results in a low luminance value, requiring careful attention to contrast ratios when paired with text or other foreground elements. According to WCAG guidelines, sufficient contrast is essential for users with visual impairments to perceive content effectively. A minimum contrast ratio of 4.5:1 is recommended for normal text and 3:1 for large text. When using Ultramarine as a background, light colors such as white or light yellow are advisable for text to ensure readability. Furthermore, avoid using this color as the sole indicator for interactive elements like links or buttons, as colorblind users may not be able to distinguish them. Supplement color cues with textual labels, icons, or other visual indicators to provide inclusive and accessible user experiences.
