The hex color #110B33, also known as Black Rock, presents significant accessibility challenges due to its very dark nature. Its low luminance creates insufficient contrast with lighter foreground colors, making text and other visual elements difficult to perceive, especially for individuals with visual impairments. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. Black Rock fails to meet these requirements when paired with many common background or text colors. To ensure accessibility, it is advisable to avoid using #110B33 as a primary background or text color unless paired with very light hues such as white or very pale yellow. Careful consideration and testing with accessibility evaluation tools are crucial to confirm compliance with accessibility standards and provide an inclusive experience for all users.
