The color #1015A4, also known as Ultramarine, presents some accessibility challenges, especially concerning color contrast. When using this color for text or interactive elements, it's crucial to ensure sufficient contrast against the background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Given its dark hue, #1015A4 requires a very light background to meet these standards. Using online contrast checkers can help verify compliance.

Proper attention to these details will improve the inclusive design of any application using this deep blue.
