The color #0B0791, a deep ultramarine, presents accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 2% means text rendered in this color on a white background would have very poor contrast, failing WCAG guidelines for minimum contrast ratios. To ensure readability, it is crucial to pair this color with very light hues, such as white or pale yellow. Alternatively, when using #0B0791 as a background, foreground elements should be in a light, contrasting color.

Providing sufficient contrast is essential for users with low vision or color blindness to perceive the content effectively and engage with the interface.
