However, its low lightness value means it requires careful consideration when used for text or interface elements, to ensure accessibility.

The color #1B05AF, a deep ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value (approximately 0.01) means that it offers very little contrast against darker backgrounds, making text or graphical elements using this color difficult to discern. According to WCAG (Web Content Accessibility Guidelines) standards, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text against its background. This color fails to meet these requirements when paired with most shades, demanding careful consideration of foreground and background color combinations. To improve accessibility, it is strongly advised to use significantly lighter colors for text or interactive elements placed on an ultramarine background. Testing with accessibility tools is crucial to ensure compliance and provide a better experience for all users.
