When specifying colors for web or print use, hexadecimal color codes offer a standardized way to ensure consistency across different displays and media.

The hex color #140729, also known as Black Rock, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value (very close to black) results in very poor contrast against most background colors, especially white. According to WCAG guidelines, sufficient contrast is crucial for readability and usability. Text or interactive elements using #140729 on a white or light-colored background would likely fail accessibility standards. To improve accessibility, consider using a significantly lighter text color, or darkening backgrounds when using #140729. Tools like contrast checkers can accurately measure the contrast ratio and determine if it meets accessibility requirements (AA or AAA). Always prioritize sufficient contrast to ensure content is perceivable and usable by all users, including those with low vision or color blindness. Large text has a slightly reduced contrast requirement.
