The hex color #090C2C, also known as Black Rock, presents significant accessibility challenges, particularly for users with visual impairments. Its extremely low luminance value results in very poor contrast against white text or backgrounds, making content difficult to read. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text to meet Level AA compliance. Black Rock fails to meet these standards in most scenarios. To improve accessibility, it is recommended to pair this color with much lighter shades or avoid using it for critical text or interactive elements. Consider providing alternative high-contrast themes or allowing users to customize color schemes to ensure inclusive design.
