The color #140A2F, also known as Black Rock, presents significant accessibility challenges, particularly concerning color contrast. Its very dark nature means that text or other elements rendered in this color require a very light foreground color to meet WCAG (Web Content Accessibility Guidelines) standards for readability. A contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Using a color contrast checker is crucial to ensure sufficient contrast. When using Black Rock as a background color, bright colors such as white, yellow, or light green may work well. If the contrast is not sufficient, consider adjusting the lightness of the foreground color or using a lighter shade of gray instead of pure black for the background.
