The color #111599, also known as Ultramarine, presents significant accessibility challenges, particularly in web design. Its dark hue results in very low contrast against standard light backgrounds, which can make text and other elements difficult or impossible for users with visual impairments to perceive. According to WCAG guidelines, sufficient contrast ratios are crucial for readability. To ensure accessibility, it's essential to pair Ultramarine with very light colors, such as white or pale yellow, to achieve a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Avoid using it for essential interface elements, such as buttons or links, unless accompanied by clear visual cues and sufficient contrast. Consider providing alternative color schemes that allow users to customize the display based on their individual needs. Proper testing with accessibility tools is essential to validate the usability of color combinations involving #111599.
