This allows for a wide range of colors to be precisely specified and displayed on digital devices.
The hex color #0a11bb, a deep, dark blue, presents significant accessibility challenges, particularly regarding color contrast. When used as a background color, text displayed on top of it must be carefully chosen to ensure sufficient contrast for readability. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Light colors like white, light gray, or bright yellow are generally better choices for text color to achieve the necessary contrast. Using a color contrast checker is essential to verify compliance. Furthermore, avoid using this dark blue for essential visual elements such as links or buttons without clear visual cues, as users with low vision may struggle to differentiate them from the surrounding content. Consider providing alternative styling options for users who require higher contrast.
