The color #1508AC, also known as Ultramarine, presents some accessibility challenges, particularly for users with visual impairments. Its dark hue results in a low contrast ratio when paired with lighter text or interface elements. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. When using Ultramarine, ensure a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text. Consider using lighter shades of yellow, white, or other high-contrast colors for text and interactive elements placed on an Ultramarine background. Additionally, avoid using Ultramarine as the sole indicator for interactive elements, as users with color blindness may not be able to differentiate it from non-interactive elements. Providing supplementary cues, such as underlines or icons, can improve accessibility for all users.
