The hex color #040398, also known as Ultramarine, presents significant accessibility challenges, primarily due to its very dark hue. When used as a foreground color, it necessitates a very light background color to ensure sufficient contrast for readability, especially for users with visual impairments. According to WCAG (Web Content Accessibility Guidelines) standards, the contrast ratio between the text and background should be at least 4.5:1 for normal text and 3:1 for large text. Given the darkness of #040398, it is crucial to test the color combination with accessibility tools to verify compliance. Failure to meet these contrast requirements can exclude users with low vision or color blindness, highlighting the importance of careful consideration and testing during the design process. Using lighter shades of blue or pairing it with a very light yellow or white can improve accessibility.
