The color #18029C, a deep ultramarine, presents accessibility challenges due to its low luminance. When used as a background, sufficient contrast with foreground text is crucial for readability, especially for users with visual impairments. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text, as per WCAG guidelines. Lighter text colors like white or pale yellow would provide better contrast.

Considering alternative color combinations or adding visual cues, like borders, can further enhance accessibility.
