The hex color #150A91, also known as Ultramarine, presents several accessibility considerations for web developers. Its dark hue means it requires careful pairing with text colors to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using a very light color such as white or light yellow for text on an Ultramarine background would likely meet these requirements. It's crucial to test color combinations with accessibility tools to verify compliance and cater to users with visual impairments. Developers should also avoid relying solely on color to convey important information; use text labels or icons to provide alternative cues. Consider providing a high-contrast theme option for users who need it.
