The color #001098, also known as Ultramarine, presents significant accessibility challenges, particularly in text-based applications. Its very dark hue results in low contrast against backgrounds, especially white or light-colored ones. This makes it difficult for users with visual impairments to read text rendered in this color. According to WCAG guidelines, sufficient contrast is crucial for readability. To ensure accessibility, it is recommended to pair this color with very light shades, such as white (#FFFFFF) or very light grays. Using tools to evaluate color contrast ratios is highly advisable before deploying this color in user interfaces. For larger text sizes, slightly lower contrast ratios may be acceptable, but testing with diverse user groups remains important. In interactive elements, ensure that hover, focus, and active states also maintain adequate contrast. Alternative color choices might be more accessible, especially if the primary goal is to convey information effectively to a wide audience.
