The color #1C0AAA, also known as Ultramarine, presents some accessibility challenges, particularly regarding text contrast. When using this color for text, it's crucial to select a foreground color that provides sufficient contrast to ensure readability for users with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text.
