When using #0400B4, careful consideration must be given to color pairings to avoid making content illegible for users with visual impairments. Using online contrast checkers is highly recommended to validate color combinations. Also, avoid using it for essential UI elements without proper contrast as it can severely impact usability. This dark blue may be more suitable for decorative elements or backgrounds if sufficient contrast is ensured elsewhere.
