Its low luminance makes it difficult to achieve sufficient contrast with lighter colors, which is essential for users with visual impairments.

When using #0B3890 for interactive elements like buttons or links, it's crucial to provide clear visual cues, such as hover effects or underlines, to enhance usability for all users, including those with color vision deficiencies.
