The color #140B8D, also known as Ultramarine, presents some accessibility challenges, particularly in web design. Its dark hue results in a low contrast ratio when paired with lighter text, potentially making it difficult for users with visual impairments to read. According to WCAG guidelines, sufficient contrast is crucial for readability. Using a lighter shade of text like white or a very light grey might alleviate this issue to some extent, but careful evaluation using contrast checking tools is essential. When used as a background, ensure that foreground elements have adequate contrast. Consider providing alternative color schemes for users with specific visual needs. Moreover, avoid using this color to convey critical information without redundant cues, such as text labels or icons, as color perception varies among individuals. Proper implementation of ARIA attributes can also enhance accessibility by providing semantic information to assistive technologies.
