It simulates the aesthetic of charcoal but incorporates a subtle bluish undertone.

The hex color #000A14, also known as Blue Charcoal, presents specific accessibility challenges primarily due to its low luminance. Its dark nature results in a poor contrast ratio when paired with many lighter colors, especially white (#FFFFFF). According to WCAG guidelines, sufficient contrast is crucial for users with visual impairments to perceive content effectively. To ensure accessibility, when using #000A14 for text or interactive elements, it's imperative to select foreground colors that provide a contrast ratio of at least 4.5:1 for normal text and 3:1 for large text (14pt bold or 18pt regular). Tools like contrast checkers can assist in verifying compliance. Additionally, consider providing alternative color schemes or themes that offer higher contrast options for users who require them. For non-text elements, a contrast ratio of 3:1 is required.
