The color #130A91, a deep ultramarine, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance and strong reliance on blue make it difficult to perceive against lighter backgrounds. To ensure inclusivity, it is crucial to use this color sparingly, especially for text or interactive elements. When using #130A91 for text, a high contrast ratio against a light background is essential, ideally exceeding the WCAG AA standard of 4.5:1.

Avoid using this color for critical information or actions without providing alternative visual cues, such as icons or labels, and always test the color scheme with accessibility tools to verify sufficient contrast for users with different visual abilities.
