The hex color #140C8C, also known as Ultramarine, presents some accessibility challenges, primarily due to its dark nature. When used as a background color, it requires very light text to ensure sufficient contrast for readability. According to WCAG (Web Content Accessibility Guidelines) standards, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Ultramarine, being a deep shade of blue, might not meet these contrast ratios with darker text colors. Therefore, it is crucial to use a color contrast checker to verify that the chosen text color provides adequate contrast. For users with visual impairments, low contrast can make it difficult to distinguish text from the background, leading to a poor user experience. Careful consideration of color pairings is essential when using this color in web design to ensure inclusivity and usability for all users.
