The hex color #090133, also known as Black Rock, presents significant accessibility challenges. Its extremely low luminance results in very poor contrast against virtually any light-colored text or background. According to WCAG guidelines, sufficient contrast is crucial for readability and usability, especially for users with visual impairments. Using #090133 as a foreground or background color without careful consideration of contrast ratios can exclude a significant portion of users.
