The hex color #10082D, also known as Black Rock, presents significant accessibility challenges, particularly for users with visual impairments. Its very low luminance value of 0.009 makes it difficult to achieve sufficient contrast against lighter backgrounds. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. When using #10082D for text or interactive elements, it's crucial to pair it with a very light color to meet these contrast requirements. Insufficient contrast can result in content that is unreadable or difficult to perceive, especially for users with low vision or color blindness. Therefore, careful consideration and testing are necessary to ensure usability for all users. Alternative color choices with higher luminance values may be preferable to improve accessibility.
