The color #05121A, also known as Blue Charcoal, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value results in very poor contrast against most background colors, including white. This makes text or graphical elements using this color difficult to discern, leading to a degraded user experience. Adhering to WCAG guidelines, a high contrast ratio (at least 4.5:1 for normal text and 3:1 for large text) is crucial.

This darker shade of blue necessitates careful consideration and adjustment to ensure content is perceivable and usable by everyone.
